liquid chromatography!!

I don't know what it is about my Slytherin play through but it's really brought back out the inner Fanfic writer in me.

I started wondering, right after I got to the "Did you just come from the Undercroft" scene, what Ominis would've said or done if MC started crying immediately after.

she gradient on my column til I elute

lmao thank you for making this bracket. I'm in my final semester of getting a BS in chem and in the capstone lab last semester we had a lab to use HPLC to determine the amino acids in a mystery sample. yes I did vote for the amino acids we found in the sample

You're welcome! Also, that HPLC exercise sounds so cool!

HPLC machines are like fighting a god who thinks that irony is the funniest shit alive even when they've done it for millenia

my morning is good, the HPLC worked perfectly until 2pm — then the instrument errors appeared again, so i’ll let the machine rest overnight, then afternoon, i processed my data and it was unexpectedly good 🥰 i also learned the conditions on when not to use the y-intercept in the calibration curve (i found a reliable source)… hence, my data i think is ready for the article our german colleagues are preparing for next month’s submission, i’ll start writing my part 💙🤍❤️ tom I’ll continue with my protein experiments —- super tired today from begging to the HPLC to start working again 😜 hence, i decided to have dinner at Leo d’Or at the centre-ville, sashimi is ❤️🍣 awesome blue sky too 💙 i look so tired in the 3rd photo haha 😂 goodnight everyone 😘 #amazingadventuresofbeaujethro #research #science #engineering #materials #biotechnology #chemistry #physics #biology #filipinoscientist #mulhouse #hplc #alsace #hautrhin #france #biomaterials (at Mulhouse, France) https://www.instagram.com/p/CpBFrxzL48f/?igshid=NGJjMDIxMWI=

Key Benefits of Cosmetic Testing:

Cosmetics testing plays a crucial role in ensuring the safety, quality, and efficacy of beauty products. Let’s explore some of the key benefits of cosmetic testing:

Safety Assurance: Identifying Harmful Ingredients: Testing helps identify potentially harmful ingredients in cosmetics. By assessing their safety, we can prevent adverse effects on the skin or body.

Risk Mitigation: Ensuring that cosmetics are free from harmful substances reduces the risk of allergic reactions, skin irritation, or other health issues.

Quality Control: Stability Testing: Cosmetics undergo stability studies to determine their shelf life and effectiveness over time. This ensures that they remain stable and perform as intended.

Consistency: Testing helps maintain consistent product quality by adhering to Good Manufacturing Practices (GMP) guidelines.

Compliance with Regulations: Regulatory Requirements: Cosmetics testing ensures compliance with regulations set by authorities such as the US Food and Drug Administration (FDA). Non-compliance can lead to serious consequences and damage brand reputation.

Consumer Confidence: Credibility: Rigorous testing builds trust with consumers. When they know that products have been thoroughly tested, they are more likely to purchase and use them.

Transparency: Brands that prioritize testing demonstrate transparency and commitment to consumer safety.

Advancements in Formulation: Efficacy Testing: Testing validates the effectiveness of cosmetic prototypes. It helps improve formulations, leading to better-performing products.

Innovation: Research aids in developing new products that meet consumer needs and preferences.

Alternatives to Animal Testing: While animal testing has been common historically, there is a growing emphasis on finding alternatives. In vitro testing and computer simulations are being explored to reduce reliance on animals.

this chromatography is awful, there are way too many peaks, who gave me this messy sample

do SPME on it or some shit before I have to kill you for ruining my column.

What is High Performance Liquid Chromatography (HPLC)

High Performance Liquid Chromatography (HPLC) is a sophisticated analytical method used to separate, identify, and quantify components within a mixture. This technique is pivotal in fields such as pharmaceuticals, environmental testing, and food safety. Introduction to HPLC HPLC is a core technique in analytical chemistry, often utilized for quality control (QC) and quality assurance (QA) in…

Lmao what happened to ur HPLC

I wish I fuckin knew what was wrong with it. Right now it keeps blowing past the safe pressure limit, and we first though it was maybe the tubing, because it was happening when it would pull from those specific slots, but we changed out all the tubing and no dice. New running theory is that something's up with the injector pump, because the other HPLC's injector pump is flat out refusing to do it's job. We don't have any spares though, and the repair guys can't come in until mid April. My research partner and I are clawing our fucking eyes out over this, because we use the HPLC for everything, so we're at a standstill for now. The only other thing we can work on atm is microtox, which is tedious as hell and I hate it.

The HPLCs have been kindof on the fritz since last spring. There was this crazy power outage on our campus and the surrounding town because of some fuck up at the power plant (I was in our science building at the time and there were people trapped in the elevator). Apparently our HPLCs were the only things in the instrument lab that weren't connected to surge protectors, idk why that is, but that's about when they started having trouble so I think they got screwed up by the surge and that it's a bigger problem than just the injector and tubing.

We thought we cleared up the original original problems from last spring, but apparently our professor never actually had anyone come in to professionally check on the HPLCs after the power surge (Stingy bastard, I know we have the grant money to do it). So yeah, they've been on and off for the better part of a year now. The past three month though have been the worst for it though. Before, we could get decent readings, we just had to be delicate. Now we cant even use them reliably.
