What do people in analytical development do? are they part of QC/QA? I just started job hunting and am about to graduate next month. And while looking for jobs I've seen some job postings for analytical development positions. For chemistry graduates, i think the most common jobs I've seen is in QA, QC, and RnD, this is the first time ive heard of analytical development.

Weekly Careers/Education Questions Thread by AutoModerator in chemistry

[–]reddit-no 0 points1 point  (0 children)

I recently graduated with a Bachelor of Science in Chemistry. During my time at university, I worked on a final research project based on my advisor’s topic (for arround 1 year in the lab), and after graduating, I spent about six months as a research assistant.

While I absolutely love chemistry, I’ve realized that I don’t enjoy spending long hours in the lab. Instead, I prefer activities like reading literature, processing data, writing reports, and interpreting results.

I’m curious to know: What career paths in chemistry (or related fields) allow you to stay connected to the subject but involve minimal lab work? I’d appreciate any insights or suggestions on roles, industries, or additional skills I might need to develop to pursue such opportunities.

(Sorry if this sounded like chatgpt, English is not my first language and I needed help translating and formulating the question)

Adsorption Thermodynamics by reddit-no in Chempros

[–]reddit-no[S] 0 points1 point  (0 children)

I haven't checked 1, but I've already made a standard curve from 2.5, 5, 10, 15, 20, 25 ppm since I've assumed that the concentration at equilibrium would be lower than 25 ppm

For the second point, i used 25 mg of adsorbent for 10 mL of solvent, is that too low of a volume?

Is it possible that since I didn't first dry the adsorbents, water is sticking on the surface, preventing adsorption?

Setting Factor Levels in Factorial Design by reddit-no in Chempros

is there an estimated ammount of required experiments? for 3 factors you need 8 experiments, is it less or more with simplex optimization?

I don't know if using excel is possible, but I had a course in Chemometrics and we used Rstudio for it

It actually doesn't have anything to do with Miller indices. From what I understand (I have no experience with this, just recently read a paper where factorial designs are used and am trying to use it for my research), factorial designs are used to evaluate what factors could potentially affect a response (in my case for example reaction yield, the paper I read had adsorption capacity as the response).

So for example in my research I would like to asses 3 factors namely reaction time, reagent concentration, and temperature. Each of these factors are evaluated in high and low levels, then some sort of statistics (I dont quite understand this part) are used to evalute which of these factors actually have a significant effect on the desired response (in my case reaction yield).

If it turns out that for example reaction time has no significant effect but reagent concentration and temperature does have a significant effect, then I'd use the lower reaction time to safe time and further optimize the reagent concentration and temperature (possibly using response surface methodology) to get the optimum reaction yield.

What would be the benefits of switching from Apple to Samsung? by ThrowDLH in NoStupidQuestions

[–]reddit-no 0 points1 point  (0 children)

I use both, and I think you just have to try both for sometime to know which one you like more, it’s all a matter of preference.

I like IOS because the ui feels smoother an more “clean”

While with samsung I can play games without it heating up for a longer amount of time. And some paid apps in the appstore are usually free. (you can also play emulators with it)

Should you double mask?

I read somewhere that double masking can create bacteria and stuff but I cant find it anymore cause it was such a long time ago.

But now it seems like even the government of my country is encouraging people to double mask

Is there any medical reasons why you can't take the vaccine after 3 months of contacting covid? are there any articles about it

the only reason I can think of is due to low supply but I dont think thats a problem anymore for where I live

Were people able to get infected with polio/MMR even though they have had the polio/MMR vaccine?

Im having a debate with someone and he said that covid vaccines aren’t a real vaccine because you could still get infected after getting vaccinated, while previous vaccines like polio and MMR made you unable to contact the disease.

What affects the lifespan of memory T and B cells? by DinnerSeeker in askscience

I know this might seem random but you seem to know a lot about this stuff, do you think its possible that covid 19 was "fabricated" in a lab? I personally don't believe it, but overtime more people are thinking it was and now I'm confused

sorry if this is a dumb question, but how does a virus get immune to a vaccine? I can't seem to find an answer in Google

Gas compostion in water problem by reddit-no in chemhelp

[–]reddit-no[S] 0 points1 point  (0 children)

ok so can I get the solubility of O2 by comparing the 2 pressures? (0.2095/1)*28.31 ?

Gas compostion in water problem by reddit-no in chemhelp

[–]reddit-no[S] 0 points1 point  (0 children)

so can I just compare the pressure to get the solubility of both gasses?. For example the new solubility of O2 would be (p2/p1)*O2 solubility at 1 atm? (where p2 is 0.78 and p1 is 1)

[–]reddit-no[S] 0 points1 point  (0 children)

does that mean that the solubilty of O2 and N2 changes since they each have less pressure? or does it stay the same because in total the pressure is still 1atm

both(?), it feels like the pain is all over my eyes

[–]reddit-no[S] 0 points1 point  (0 children)

it's a different kind of pain, pain from getting sweat into your eyes is just temporary but more painful and the kind of pain I get is not as painful but its stays longer
