GC–MS Used to Assess Surgeons' Health Risks
The American Urological Association has used a GC–MS method to determine the health risks faced by surgeons due to toxic by-products in surgical smoke.
The American Urological Association (Linthicum, Maryland) has used a GC–MS method to determine the health risks faced by surgeons due to toxic by-products in surgical smoke. The association has published findings from the Republic of Korea, where scientists looked at smoke produced in prostate vaporisation and transurethral resection.
The team analysed samples from six procedures using GC–MS, looking for potentially harmful chemicals. In their samples, they discovered potential carcinogens, along with chemicals associated with irritation to the skin and eyes and depression of the central nervous system.
Based on these findings, the association is calling for “a higher-quality filter mask, smoke evacuation device, or smoke filter” to be deployed during surgery for the protection of both the operating staff and the patient.
An LC–HRMS Method for Separation and Identification of Hemoglobin Variant Subunits
March 6th 2025Researchers from Stanford University’s School of Medicine and Stanford Health Care report the development of a liquid chromatography high-resolution mass spectrometry (LC–HRMS) method for identifying hemoglobin (Hb) variants. The method can effectively separate several pairs of normal and variant Hb subunits with mass shifts of less than 1 Da and accurately identify them in intact-protein and top-down analyses.
The Next Frontier for Mass Spectrometry: Maximizing Ion Utilization
January 20th 2025In this podcast, Daniel DeBord, CTO of MOBILion Systems, describes a new high resolution mass spectrometry approach that promises to increase speed and sensitivity in omics applications. MOBILion recently introduced the PAMAF mode of operation, which stands for parallel accumulation with mobility aligned fragmentation. It substantially increases the fraction of ions used for mass spectrometry analysis by replacing the functionality of the quadrupole with high resolution ion mobility. Listen to learn more about this exciting new development.
