Restek has launched its next-generation RMX gas chromatography columns featuring TriMax deactivation technology. The columns are designed for trace-level detection of problematic active analytes.
Restek positions RMX GC columns as delivering maximum inertness, sensitivity, and durability for demanding applications. The columns target challenging compound classes such as acids, bases, and alcohols, where conventional deactivation can compromise peak shape and reproducibility.
TriMax technology creates an exceptionally inert, contaminant-free surface that eliminates residual active sites. Restek links this surface chemistry to symmetrical peaks, trace-level sensitivity, extended column lifetime, and performance recovery after aggressive thermal cycling and heavy matrix contamination.
“TriMax deactivation represents truly groundbreaking research,” notes Danny Shollenberger, Principal Scientist at Restek. He describes the use of novel reagents engineered specifically for gas chromatography and a precisely controlled process that forms a dense, three-dimensional network of bonding, crosslinking, and deactivation. Restek attributes exceptional trace-level reliability and superior inertness to this approach.
Restek developed RMX columns in response to chlorinated solvent bans, method consolidation pressures, instrument lifetime limitations, and the need for picogram-level sensitivity. Ramkumar Dhandapani, PhD, Director of Product Management, points to these pressures as key drivers behind the RMX design.
According to Restek, the high sensitivity and consistent performance of RMX columns allow laboratories to meet data quality requirements for longer periods, expand analyte lists, and reduce solvent use through scaled-down sample extractions.
