Wow, quite an impressive setup. They used an LTM (Low Thermal Mass) Series II for rapid heating on an Agilent 7890 with an SCD, NCD, 5975C MSD, a Capillary Flow Technology (CFT) Deans switch, two CFT splitters, and retention time locking. As if that weren't enough, they used the CFT devices to implement backflushing. Whew! 😎 Not familiar with LTM? Check it out at http://bit.ly/4gwMMFy.

This application note demonstrates the use of an Agilent 8890 GC system coupled with an Agilent 7010 GC/MS triple quadrupole mass spectrometry system to detect and quantify ethylene oxide (EtO) and 2-chloroethanol (2-CE) simultaneously in foodstuffs such as flaxseed, cumin powder, and red chili powder. Sample preparation was done using QuEChERS extraction and a dispersive cleanup process followed by injection into GC/MS/MS through liquid injection. A limit of quantification (LOQ) of 10 ppb for both compounds was achieved in matrix. Average recoveries ranged from 75 to 86% for both compounds. Read more: https://lnkd.in/dzqq4RQk

Breakthrough developments for heavy metals (Cd, Pb, As, Hg) analysis in food: There is noo need to do acid digestions and ICP-MS for Cd and Pb analysis in food matrixes. An innovative, portable XRF Emax and Zmax analyzers provide Cd and Pb analysis down to 30 ppb levels in food. Non-destructive and minimum sample preparation, get results in 1-10 minutes. Amazing and Unreal, try Zspec

#Analizer #PH #buffre Buffer solutions are needed as an indispensable tool for maintaining an accurate pH measurement. Buffer solutions are used as references points for calibration and adjustment of pH measurements to compensate for again and deterioration. pH buffer solutions are mixtures of weak acids and the salt of these acids with a strong base, or mixtures of weak bases and the salt of these bases with a strong acid. Consequently, if the buffers are not accurate themselves, the calibration serves no useful purpose. Buffers are classified in three categories. The main difference between the different types of buffers is the accuracy and buffer capacity.
