Other Inlet Supplies

Agilent’s specialty inlet options support a wide range of GC applications, from highly precise liquid injections to robust packed-column workflows. Chrom Tech supplies all genuine Agilent components required to maintain and optimize these inlet types, ensuring reliable performance, reproducible injections, and long-term system integrity.

Cool On-Column (COC) Inlet Supplies

Cool On-Column injection provides the most direct, discrimination-free transfer of sample into the column, helping minimize thermal degradation and preserve analyte integrity. Chrom Tech carries the full selection of Agilent COC inlet supplies needed for setup, routine operation, and long-term maintenance.

Programmable Temperature Vaporizing (PTV) Inlet Supplies

Agilent PTV inlets combine the benefits of split, splitless, and on-column injection techniques. Samples are introduced into a cool liner to avoid syringe needle discrimination, then vaporized under controlled temperature programming. Chrom Tech offers genuine Agilent PTV liners, seals, and accessories to support precise vaporization and reproducible sample transfers.

Purged Packed Inlet Supplies

Designed for gas-solid chromatography and applications where ultra-high efficiency is not required, Agilent’s purged packed inlets provide a simple, robust pathway for packed-column GC. Chrom Tech supplies OEM components for routine maintenance, ensuring stable carrier flow, minimal dead volume, and consistent column protection.
