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.
Detecting Hyper-Fast Chromatographic Peaks Using Ion Mobility Spectrometry
May 6th 2025Ion mobility spectrometers can detect trace compounds quickly, though they can face various issues with detecting certain peaks. University of Hannover scientists created a new system for resolving hyper-fast gas chromatography (GC) peaks.
University of Oklahoma and UC Davis Researchers Probe Lipidomic Profiles with RP-LC–HRMS/MS
May 6th 2025A joint study between the University of Oklahoma Health Sciences Center (Oklahoma City, Oklahoma) and the UC Davis West Coast Metabolomics Center (Davis, California) identified differentially regulated lipids in type 2 diabetes (T2D) and obesity through the application of reversed-phase liquid chromatography-accurate mass tandem mass spectrometry (RP-LC-accurate MS/MS).
Automated Sample Preparation (ISO 20122) for MOSH/MOAH in Seasoning Oils
May 6th 2025This work presents an Automated Sample Preparation procedure for MOSH/MOAH analysis of Seasoning Oils. We compare results from a manual epoxidation procedure compliant with DIN 16995 with results based on fully automated sample preparation (epoxidation and saponification) compliant with ISO 20122. In both cases, online clean-up via activated aluminum oxide (AlOx) are used to remove interfering n-alkanes from the MOSH fraction during the HPLC run. Automated data evaluation using a dedicated software (GERSTEL ChroMOH) is presented.
