Students I supervised last school year gave me a rafting trip as a present with them for my birthday in May and on this Friday we went to Võhandu river for this trip. Altogether we passed 20 km containing both quite slow flow parts but also some cascades. Slow parts, though not that adventures, taught […]
Today I would like to introduce you to two books that I find very valuable and that can be freely downloaded from the internet. The “Five keys to successful LC methods” and “Controlling selectivity in reversed-phase LC” are collections of articles published in LC/GC in the section “LC Troubleshooting” by John W. Dolan. It’s useful […]
In my statistics course, similarly to I guess all other teachers concerned in calibration, I teach that for instrumental analyses weighted linear regression should be used. Why? Non-weighted linear regression (the one we can use with LINEST, SLOPE and INTERCEPT in excel) assumes same signal precision (repeatability standard deviation in other words) for all concentrations […]
From 20th to 29th of July 47th International Chemistry Olympiad (IChO) was held in Baku, Azerbaijan. All together 290 form 75 countries solved 3 practical and 8 theoretical tasks. This Olympiad was definitely one of the hardest in IChO history, most probably being hard to solve for a masters student not only for high school […]
I started writing this blog to share with you some fascinating stuff I come across every once in a while. I try to cover not only the research of me and my co-workers but also other fabulous scientific papers. Also I give some practical tips concerning statistics, optimization of analytical methods (especially LC and MS) […]
