FTIR

After so many complaints about me not updating my blog, here am I again trying to populate it with words. Anyway, had the only lab for today, Pharm Analysis lab. We're playing with FTIR. For the benefit of those who haven't do the experiment yet, it means Fourier Transform Infra Red spectroscopy. What it actually does is it shines infra red light across your sample, and the absorbance by your sample is recorder, in the form of IR transmittance. Anyway, we're taught how to prepare a Nujol mull as well as potassium bromide disk of the "unknown" sample, which turns out to be paracetamol. Do take note that we're not supposed to use Nujol mull when we're testing for paracetamol as they have similar absorbance peaks. We're using paracetamol this time round as it's for demonstration purpose only.

Anyway, here's the potassium bromide disk that I made.

The disk is the one I'm holding. LOL

More and more work pilling up, SOAP, sponsorship calls, lab reports, bazaar matters, tutorials etc. Luckily Chinese New Year is coming soon, and mid semester break two weeks after that :P
