You guys should do a criticality assessment that one. Maybe a cross-functional team can go through the matrix during a few lunchtime meetings.

Shrieking Muppet posted:Just had an argument with my boss over buying a cheap hygrometer to put in our new glove box so that we would know when it’s dry enough to use. Her response was we don’t need one because someone would write it down in their notebook and this wouldn’t be calibrated. When I asked how would we know if the box was sufficiently purged with nitrogen to know if it was dry she said we purged it with nitrogen and the O2 meter would tell us when that was done. Since our procedure says to weigh under nitrogen that’s all we have to do.

RadioPassive posted:Does humidity matter? If not, I'm with your boss on this one. Yeah whole point of weighing under nitrogen is to ensure samples remain dry or make the analyst suffer but I’d like to hope it’s the first reason. Dik Hz posted:I work in an industry where humidity absolutely matters. We have spent hundreds of thousands of dollars on humidity controlled chambers. It's a rare day when our expensive hygrometers are within 5% of each other on relative humidity. A cheap hygrometer is less useful than sticking your hand in there and seeing how it feels. The O2 sensor is going to be way more accurate than a cheap hygrometer. Huh, I would have assumed the expensive ones were more accurate and precise. Guess the O2 meter makes more sense then. This might have been explained to my boss since she insisted the O2 sensor was all we needed but couldn’t give me anything past “sample paperwork says we weigh under nitrogen” as to why it was all we needed.

Sorry, I come from a GMP environment where you never generate more data than you need, and you absolutely do not make a measurement unless the paperwork calls for it. If the procedure document says "we weigh under nitrogen" and nothing about humidity, then you ignore the humidity and take it up with QA if you think that's a problem.

Any advice for someone who can't seem to find a laboratory job despite applying for every lab job within a 45min drive for the past 5 months? I know someone who's applied for 100+ lab jobs after relocating to a new city and hasn't gotten a single callback despite having 5 years of laboratory experience. He did mostly heavy metals testing in water and soil at his old job. Admittedly he's applied for some manufacturing and pharmaceutical lab jobs which are a bit outside of his skill set at the moment but he's applied to a decent number of jobs that sounded perfect for him. He's interested in a more managerial or supervisory role if he can find a position like that as he has experience managing his own lab but has been basically applying for everything vaguely reasonable, including grunt work. He's been networking through local groups and linked-in but is going to step his game up actively seeking out and connecting with hiring managers from the companies he's applying to through linked-in. He's reached out to everyone he knows professionally and has also gone to a local career center for help making sure his resume is good. He's now working to make sure he hits ATS keywords on his resumes by using a ATS scanning service and really working to tailor them for each job. Anything else he should try that he's not?

Management sees non-PhD lab work as mundane, and therefor prefers to automate, outsource, or just train someone from scratch.

We outsource testing out of the country a lot of the time, then get questions why it's taking 4 weeks to get analytical results. It's not my fault it takes weeks to sample and ship something to India, and god forbid there is a temperature excursion along the way...

Yeah, at the company I work at the chemistry group has gone from 20 to 14 and management doesn’t feel like we need any new hires. When I first started, someone told me they were outsourcing the synthesis of a challenging natural product. My response was”Wow, I can’t believe a company would agree to make that”. Nope, the third party gave up a year later.

Like I understand industry wide that automating or outsourcing is common but a lot of the positions he's applying for are ones that he exactly fits the bill for. Definitely he's applied for some low tier jobs and some that are a bit of a reach as well, but most of them want 3+ years of lab experience, which is what he brings to the table. So its not that they're aren't any reasonable looking laboratory positions being posted, which could be explained by automation/outsourcing if that were the case, but that he's applying to lots of positions that fit his skillset and not hearing anything back. I understand just wanting to train someone from scratch for the low tier positions but that doesn't work for position that require years of lab experience. Does anyone have advice on what he should look into if he chooses to further his education? He's most interested in bioremediation so it seems like a M.S. environmental engineering might be the best to meet that goal, but he's considered a masters in chemistry too. I'm also curious what education is needed to fit the bill for more lucrative laboratory positions.

For entry level, they want a new college grad with high GPA to train. For 3+ years, especially if they have a lot of applicants, they will go with someone who’s already used the specific equipment for the specific sample type(protein, cells, small Molecule, etc). Only way around that is to be internally recommended.

JibbaJabberwocky posted:Okay that makes sense, thanks. The problem is that lab-adjacent jobs will usually want lab experience. Examples are lab manager positions, schedulers, quality oversight roles, etc. If you have technical experience, you may be able to get an in-house technician / calibration role for instrumentation stuff. That's a bit too far away from adjacent I think, but it's possible. Most adjacent roles will want someone who already has experience with the main role, though, so not too good of odds there.

Which one of you goons is this? https://www.sciencedirect.com/science/article/pii/S2352409X19305371 quote:In order to procure the necessary raw materials for knife production, one of us (M.I.E.) went on a diet with high protein and fatty acids, which is consistent with an arctic diet, for eight days (Binford, 2012; Fumagalli et al., 2015) (Table S1). The Inuit do not only eat meat from maritime and terrestrial animals (Arendt, 2010; Zutter, 2009), and there were three instances during the eight-day diet that M.I.E. ate fruit, vegetables, or carbohydrates (Table S1).

Got asked today about getting trained in Mass spec so I could work with the mass spec group to run samples. I wouldn’t be transfers to the mass spec group just running reference standards so that they can handle their work. Decided that since that group is run by a slave driver who treats her team like poo poo I should decline the offer since I know I would be thrown into that group when the next reorg happens if I knew MS.

Since there seem to be a lot of HPLC people around here, I am wondering whether anyone have good recommendations for a HPLC-MS system. Chromatographically there are no heavy requirements, since currently we are running this fine on 10-20 year old LC-MS systems, as well as on a new Sciex system. What we are mostly looking for is supporting software that allows for keeping track of 25-50 compounds in a mix and highly automatized and stable analysis of weak and broad peaks. The system is supposed to run 1000-10000 compounds in mixes. Also, since there are ELN sellers here, anyone got a recommendation for a good one that is customisable to cover anything from cell expressions to protein crystallization and NMR. Preferably self-hosted on our network and must be Mac-friendly.

IDBS seems to be the golden standard for ELN and the other big name I can think of is BIOVIA (they bought Accelrys). I don’t have any first hand experience with either product but all of my customers love IDBS so I’d start there with the understanding that they will probably be on the upper end price wise. I sell LIMS, so a slightly different product, but as the markets/products converge we are seeing and competing with ELN vendors more often.

I've been migrating our old, incredibly lovely FileMaker Pro database/biorepository into FreezerWorks, and let me tell you it's impressive to see the amount of absolutely hosed data my predecessors thought was acceptable. So many "Y" entries in numeric fields that I kind of just want to.. die.

My company switched from paper notebooks to Biovia last year. Overall it’s works, very searchable. The biggest problem, and something that might be a deal breaker for crystallization data, is that the data archives are limited to files less than 100 Mb. You can upload as many 100 Mb files as you want though. So stupid.

Dik Hz posted:Why do you need big files for crystallization data? You don't need to store the image files, do you? Just the reflections.db We store all image files since we never know when we need to go back for reprocessing. Currently we have one project from 2014 that is going to the PDB database and which needed reprocessing. The Eiger detectors that are becoming standard on all big beam lines also create large amounts of data. I will check out the Biovia, the max upload I don’t see as a problem as we would probably keep actual image files separate.

Dik Hz posted:I get the impulse, but aren't your image files already processed to the pixel anyway? Might be, I only cheat at crystallography and X-ray. My coworkers process from image files using different software for isotropic and anisotropic data so we need the image files. As storage space is cheap and my coworkers have no interest in sorting the data, this is currently the working solution.

Tunicate posted:Raw image files add up fast, i do optical imaging with a canon camera on a scope, and it's 300-400 MB per 10 second experiment A normal 4 h session at a beamline generates on average something like 500 Gb data, mostly images. Funny fact, nowadays the sample changer takes longer than the actual data collection. That is of course on a good beamline.

So my boss, the VP of R&D, proposed trying to make a superhydrophobic coating out of a system composed of a acrylic emulsion in water and a water-soluble amine-based polymer. When I pointed out that water soluble polymers generally don't make hydrophobic coatings, I added the obvious, "unless you react away all hydrophilic groups." Which of course, would be ridiculous in a coating, and especially ridiculous with amine chemistry. He just smirked and leaned back and whispered "Unless...." like I was just finally grasping his brilliant idea and he wasn't just saying the word "superhydrophobic" in front of execs. He didn't get the first part, had no idea why the second part would be true, there's no reason why superhydrophobicity would be a useful property for our application, and it's just dumber the further down you go.
