Alpha hydroxy garbage

This is kinda funny. After studying organic chemistry, whenever those commercials came on TV about "alpha hydroxys" in skin creams and stuff I would laugh and say that doesn't mean anything. I tried to explain to my girlfriend that the term alpha hydroxy just describes a location on a molecule, like the next carbon over from something has an alcohol bonded to it. In other words, the alcohol (hydroxy) is alpha (next to) something, but you can't really tell what that something is when you say alpha hydroxy.


Glycolic acid

Some of the commercials say "alpha hydroxy acids". This makes much more sense, turnes out, there is a group of molecules called alpha hydroxy acids. And they do have an effect on skin.

Another thing that tickles my fancy is seeing all those little multi-colored beads mixed in and suspended in the face wash or shampoo. That is actually some hot research because just the way it looks sitting on the grocery store shelf makes people buy it. So there were actually scientist out there trying to find out how to suspend little colored balls in a hair gel, making and spending loads of money. It's just the way it goes. Kinda seems like a waste of scientific talent to me, maybe the project only took a couple years.

Next up, beta hydroxy acids.

On global warming from a sceptical chemist

I got into a very interesting and controversial conversation while on a trip to Chicago with a jaunt to Green Bay last week.

The topic of global warming came up from someone who believes it is happening and that something must be done about it. I made a little remark about how I was still somewhat sceptical of the whole global warming argument. And the reaction was surprisal, especially me being a scientist and everything. They went on to talk about how scientist views are being put down or hushed by Washington government. That in itself is very alarming and really requires its own post.

It gets real messy when politics get mixed in with science. You really don't know whose views are swayed by whatever. Really, what I think the problem is, I can't find information on the subject that I don't feel has been politically influenced. What I have read is mostly from science articles on the web that are conflicting. That is how it appears to me, is that scientist actually don't agree on global warming.

Instead of commenting about how I know nothing about global warming (I admit, I'm not an expert), please give me a link to some scientific literature about global warming that you believe to be the truth. I mean the facts, some evidence, you know, experimentation. I'll take a sceptical look at computer models.

By the way, I noticed I made an appearance on the Mass Spectrometry Blog.
An interesting blog by a fellow mass spectrometerist.

Phosphorus and methamphetamine

A great idea, all this time, and no comments. Well, fellow mass spectrometrists of the world, I've got some new things to talk (write, type, blog) about.

Short side note, anyone ever hear a hissing noise comming from the torch box. It's not an electrical arc or I just can't see one. I have produced an electrical arc on the torch itself before and gave it a nice melted dimple. This noise seems to be something else, almost sounds like gas or water blowing out a small hose, but I think if that was the case, things wouldn't be working as well as they have been. No visible damage or drift caused by noise.

Next up, I just got word that I will be analyzing some samples from a meth lab bust. I'll be looking for phosphorus. I imagine I'll find some since the samples are taken from powder made by grinding up match heads. So, I don't think I'll have any actual meth in the lab, sorry. I know detection limits are crappy, like 1ppm, anyone know about any interferences or any other problems analyzing phosphorus.

Methamphetamine has quite a history. It's a farely new drug, first synthesized in 1919 in Japan. It was distributed during WWII to Nazi soldiers as a stimulant. In the 50's it saw such uses as a cure for narcolepsy, post-encephalitic parkinsonism, alcoholism, depression, and obesity. What a wonder drug back then. Made illegal sometime in the 80's when its recreational use started up.
Easily made by even non-chemists from pseudoephedrine hydrochloride, various different procedures found in chemistry journals or sketchy websites. There is a wealth of information found on Wikipedia (who checks the facts on this website?)
