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.
The Complexity of Oligonucleotide Separations
January 9th 2025Peter Pellegrinelli, Applications Specialist at Advanced Materials Technology (AMT) explains the complexity of oligonucleotide separations due to the unique chemical properties of these molecules. Issues such as varying length, sequence complexity, and hydrophilic-hydrophobic characteristics make efficient separations difficult. Separation scientists are addressing these challenges by modifying mobile phase compositions, using varying ion-pairing reagents, and exploring alternative separation modes like HILIC and ion-exchange chromatography. Due to these complexities, AMT has introduced the HALO® OLIGO column, which offers high-resolution, fast separations through its innovative Fused-Core® technology and high pH stability. Alongside explaining the new column, Peter looks to the future of these separations and what is next to come.
