I love the grips!
Damn, I wanna work at Tsinghua. I'd happily be a spy or whatever for the chinese government if I got to work there.
The preview movie was fantastic. I'm wondering if they're going to use any of the backstory animation from the movie, or if they are going to leave that as a purely movie thing. I'm excited to see what people think about Nyaan, cause the takeaway both my wife and I had was that

she acts like a complete poser, and it seems like that might be her character's arc
Communism can never succeed until it has trading cards of local exemplary workers.
Unsweetend shreaded wheat is the only good cereal imo (besides wheatabix but those are real expensive here). Cheap as dirt and tastes fine with one ingredient, wheat.
Na but if you play it let me know if it's good. I've been interested in it.
I think it is important to seperate the two ideas you're referencing. Testing purity requires different techniques than concentration testing.
You could theoretically estimate the purity of your compound of interest if you had a fairly good idea of what the impurities were. Spectroscopic techniques are generally used for identification of the impurity causing compounds and not for purity testing.
On the specific device you mentioned: I don't believe that device would be useful/sufficient for two reasons. Firstly, like most inexpensive/small spectrometers, the spectrometer linked is a visible light spectrometer. Visible light spectroscopy is not very useful for organic compounds as organic compounds don't tend to absorb in the visible region (which is why your feedstock is a white powder). This would be the primary limiting factor in regards to concentration testing. The other problem with that kind of device is the limited wavelength resolution which would make it rather difficult to identify impurities.
If you wanted to get a good idea of the impurities of a feed stock, the best options would be GCMS or HPLC. HPLC would probably be the better of the two for a small scale chemical operation, given that it doesn't need a constant supply of pure gas like GCMS.
Administration techniques are your best friend here. You must be converting your feedstock into an oraly administered drug. If you don't have the equipment and/or supply chain information to ensure what you are putting in your body doesn't contain harmful side products, you absolutely must use your body's natural filtration system to protect yourself.
Without reading a lot more and having a good idea of how the feedstocks are synthesized, I wouldn't feel comfortable administering these compounds without some kind of atomic absorption spectroscopy to look for heavy metal reminants from the synthesis process. It is entirely possible that the methods used to synthesize these compounds don't ever use possibly toxic compounds, but I don't know and cannot say.
I know, it's me, I'm the 75%.
Ah, that makes sense.
I could not make it through Maria Holic, the gender takes were really bad. I'm impressed if you did.
