Master Preclinical Toxicology with HRMS

Unlock the highest level of confidence in your preclinical toxicology studies by harnessing the capabilities of High-Resolution Mass Spectrometry (HRMS). While traditional methods lack the sensitivity needed to distinguish subtle differences in mass-to-charge ratios (m/z) between ions, particularly on low-resolution instruments, HRMS provides a substantial advantage, resulting in robust results that surpass conventional methods.
 

Predict Toxicity Earlier in Development

HRMS enhances quantitative bioanalytical studies, including biomarker analysis & validation, enriching drug metabolism and pharmacokinetic (DMPK) assessments, and time profiles. It enables you to achieve the sensitivity and precise calibration necessary to accurately reflect both subtle and significant effects of your products on endogenous molecules at preclinical stages of development.

Overcome Matrix Effects

Labs often deal with problems like interference, cross-reactivity, and choosing internal standards for accurate calibration in qualitative & quantitative bioanalytical studies. HRMS effectively addresses the challenges posed by matrix effects and the fluctuating ionization and fragmentation efficiency of various compound classes in complex mixtures. Discover how Sannova's Z factor approach and good laboratory practices (GLP) synergise with HRMS methods to ensure that no significant effect evades detection.
