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.
Maximizing Cannabinoid Separation for Potency Testing with LC
April 7th 2025Researchers from the Department of Chemistry at Western Illinois University (Macomb, Illinois) conducted a study to optimize the separation of 18 cannabinoids for potency testing of hemp-based products, using liquid chromatography with a diode array detector (LC–DAD). As part of our monthlong series of articles pertaining to National Cannabis Awareness Month, LCGC International spoke to Liguo Song, the corresponding author of the paper stemming from this research, to discuss the study and its findings.
How Many Repetitions Do I Need? Caught Between Sound Statistics and Chromatographic Practice
April 7th 2025In chromatographic analysis, the number of repeated measurements is often limited due to time, cost, and sample availability constraints. It is therefore not uncommon for chromatographers to do a single measurement.
