About InertCap 5MS/EX

 

Unparalleled Performance in GC-MS

 

InertCap 5MS/EX is a premium-grade GC-MS column engineered for the highest analytical demands. With world-class ultra-low bleed and outstanding inertness, it ensures reliable quantitation and sharp peak shapes even for highly active or thermally labile compounds. Ideal for trace analysis and sensitive applications, InertCap 5MS/EX delivers unmatched performance in both routine and advanced GC-MS workflows.

 

    Impact of Mobile Phase pH on Selectivity

    These chromatograms demonstrate how changes in mobile phase pH influence the selectivity and resolution of analytes. Inertsil Hybrid-C18 of hybrid silica gel allows stable performance across this wide pH range without loss of efficiency and reproducibility.
