Applications ionBooster

ionBooster in Forensics

Ethyl-Glucuronids (EtG and EtS) are markers for alcohol misuse. The ionBooster source yields a sensitivity improvement of factor 10 for EtG, compared to a standard ESI source. For details, please refer to application note ET-28.


ionBooster in Food Safety

Extremely sensitive analytical methods are required for accurate low-level identification, and quantitation of zero-tolerance compounds in food. The broad-spectrum antibiotic Chloramphenicol (CAP) is such a compound. Determination of CAP is often performed by LC-MS/MS using MRM measurements on traditional triple-quadrupole instruments. Using the ionBooster, CAP can be determined in an LC-MS full scan method for lower limit quantification and confirmation on a maXis UHR-TOF system, without compromising other analytical information.
The ionBooster achieves a Limit of Quantitation (LOQ) more than 100 times lower than the minimum required performance level (MRPL).
