The thriving terror activity is a menace to our society. To mitigate this, there dire need of upgraded and innovative analytical techniques for forensic analysis explosives. complexity in the matrix, restrictions sample quantity ambiguity data interpretation are different challenges that scientist face. solution these problems lies upgradation extraction technique, screening technique & con...
• Combined used of UV and MS data allow for method validation as ICH stability indicating. signal showed clearly better parameters validation. HRMS was crucial to assure specificity. (RP)UHPLC/UV-(HESI/Orbitrap™)MS nivolumab quantification is shown the first time. Nivolumab isoform profile identified by mass spectrometry. (Opdivo®) a fully human immunoglobulin G4 isotype approved treatment many...
A proposal has been developed by the Agricultural Chemical Safety Assessment (ACSA) Technical Committee of the ILSI Health and Environmental Sciences Institute (HESI) for an improved approach to assessing the safety of crop protection chemicals. The goal is to ensure that studies are scientifically appropriate and necessary without being redundant, and that tests emphasize toxicological endpoin...
Liquid chromatography - high resolution mass spectrometry (LC-HRMS) developed to screen some residues in rice. Pesticides, aflatoxin B1, B2, G1, aflatoxin G2 and quaternary ammonium surfactants were detected by the optimized method. Rice samples extracted cleaned QuEChERS then analyzed QExactive system with HESI ionization source for both negative positive modes. The&...
