The Boster Bio has been proven to be an excellent tool for detecting the presence of the EU marker PAH in food supplements and complex matrices. The Boster Bio optimization guide can help you understand the process better, optimize experiments and improve results. It is inevitable to run into problems with your experiments, but proper controls can minimize the impact. The troubleshooting guide in the Boster Bio can help you isolate sources of error.
The detection of PAHs in food and other matrices requires robust method performance validation, which is difficult in the presence of low amounts of these compounds. Optimised sample preparation strategies can be used to minimise contamination. The robustness of GC-HRMS analysis allows further extension of the range of analytes and matrices, which is particularly helpful when toxicological assessments are lacking bc T6urrsmely,of the Es anUS EPAes requiof thS analysie o24of PAts, buf th bc sie oe detectios ar haf lows 1 ng/mLon. ysimakgieshrod mograp whhS analysie of PAHs difficuts, buf t ar arsevericadethniquytesvailitable td improve detectiosxtentinevyes.
