Chromatography Accessories (HPLC & GC)
GC Columns — Packed and Capillary
Column/Instrument Specifications & Methodology
GC columns are supplied in packed and capillary formats for gas chromatography applications. Capillary columns are selected by bore, film thickness, and stationary phase chemistry for separations; packed columns are used for preparative or specialized separations. Buyers choose columns to match analyte classes and oven temperature programming needs.
Throughput, Compatibility & Reagent Ecosystem
Column selection impacts sample throughput and method robustness. Procurement includes spare columns for method validation and routine replacement schedules.
HPLC Syringes
HPLC Syringes for Chromatography Sampling
HPLC Syringes are precision instrument components used to transfer and inject samples in HPLC workflows. These syringes are sized and calibrated for accurate micro- and millilitre-volume handling. Laboratory procurement teams rely on consistent plunger action and low dead-volume design to protect column integrity and ensure repeatable injections. Sourcing decisions focus on barrel material, luer fitting compatibility, and dimensional tolerance to match autosampler and manual-injection needs.
Material, Compatibility & Supply Terms
Typical syringe materials include borosilicate glass barrels and PTFE or stainless-steel plungers where specified. Compatibility with autosampler rotor seals and low-extractable materials is a key selection criterion. Available for bulk orders and scheduled replenishment, these syringes suit QC labs, method development groups, and routine analytical departments seeking consistent batch-to-batch performance.
GC Syringes
Column/Instrument Specifications & Methodology
GC syringes enable precise sample injection for gas chromatography and are available in a range of volumes and needle gauges. Selection depends on injection volume requirements and injector design. Laboratories stock syringes to support method reproducibility and instrument maintenance.
Throughput, Compatibility & Reagent Ecosystem
Pack sizes align with expected replacement rates and calibration schedules. Procurement should match syringe specifications to injector requirements for consistent performance.
HPLC Columns
Column/Instrument Specifications & Methodology
HPLC Columns are stationary-phase components designed for chromatographic separation in analytical and QC labs. Columns are specified by bonded phase chemistry (C18, C8, phenyl), particle size, and column dimensions to match method requirements. Buyers evaluate column selectivity, theoretical plates, and pH stability for method transfer and routine analysis. Selection balances resolution needs with backpressure and instrument capability.
Throughput, Compatibility & Reagent Ecosystem
Choose particle size and column length according to throughput targets and instrument pressure limits. Columns must be compatible with common UHPLC/HPLC systems and solvent systems used in QC. Bulk procurement options and scheduled replenishment support laboratories that run high sample volumes and frequent column replacement cycles.
HPLC Column Storage Cabinet
Column/Instrument Specifications & Methodology
The HPLC column storage cabinet is designed to store chromatography columns securely and protect them from mechanical damage. Cabinets include configurable shelving and padded supports to match column lengths and diameters. Procurement selects configurations that align with column inventory and lab footprint.
Throughput, Compatibility & Reagent Ecosystem
Cabinet capacity and internal fittings are chosen to match typical column inventories for QC and method development. Buyers consider modular shelving for future expansion.
