Chromatography Instrumentation

Chrom Tech is an experienced distributor of laboratory instrumentation and fluid delivery systems designed to support reliable chromatography performance. From precision HPLC pumps to bench-top instrumentation and on-demand gas generation, our portfolio is engineered to help laboratories maintain stable flow, consistent pressure, and uninterrupted operation.

This category is organized into three core subcategories that support complete analytical workflows — from solvent delivery to system control and laboratory gas supply.

HPLC Instrumentation

Bench-top LC instrumentation including fraction collectors, degassers, heaters, and complementary modules that expand system capability. Designed for method development, preparative workflows, and routine analytical operation with dependable performance and compact lab footprints.

Chrom Tech Pumps

Positive-displacement piston pumps engineered for stable, pulse-minimized flow and accurate solvent delivery. Available in isocratic and gradient configurations to support reproducible retention times and long-term method reliability.

Gas Generators

Key Definitions â–¶
Positive-Displacement Pump
A piston-driven pump that delivers precise, controlled solvent flow independent of system backpressure. Commonly used in HPLC systems to ensure accurate flow rates and reproducible retention times.
Isocratic Pump
A pump configuration that delivers a single solvent composition throughout the run, providing stable baseline conditions for routine analytical methods.
Gradient Pump
An HPLC pump capable of dynamically mixing multiple solvents during a run, allowing controlled changes in mobile phase composition to improve analyte separation.
Degasser
A device that removes dissolved gases from mobile phase solvents to prevent bubble formation, baseline noise, and pump cavitation in liquid chromatography systems.
Fraction Collector
An instrument module that automatically collects separated compounds as they elute from a chromatographic column, commonly used in preparative or purification workflows.
Gas Generator
A laboratory device that produces high-purity gases (such as nitrogen, hydrogen, or zero air) on demand, eliminating the need for compressed gas cylinders and improving laboratory safety.
Flow Stability
The ability of a pump system to maintain a consistent and pulse-minimized solvent flow rate, directly influencing retention time precision and chromatographic reproducibility.
Frequently Asked Questions â–¶
How do I choose the right HPLC pump for my application?
Pump selection depends on required pressure range, flow rate stability, gradient capability, and application type (analytical vs. preparative). Chrom Tech helps laboratories evaluate solvent composition, system backpressure, and method sensitivity to recommend the appropriate positive-displacement pump configuration.
What are the advantages of on-demand gas generators over cylinders?
Gas generators provide continuous, high-purity gas without cylinder handling, delivery delays, or safety concerns associated with high-pressure tanks. Chrom Tech supplies generator solutions that reduce operational risk while improving uptime and long-term cost control.
Can Chrom Tech help integrate instrumentation into existing LC systems?
Yes. Chrom Tech provides consultative guidance to ensure compatibility between pumps, degassers, heaters, fraction collectors, and existing LC platforms. We help simplify integration while maintaining method reproducibility and regulatory confidence.
How does flow stability impact chromatographic results?
Stable flow minimizes retention time variability and improves peak reproducibility. Pulse-dampened, precision-engineered piston pumps supplied by Chrom Tech are designed to maintain consistent solvent delivery across a wide pressure range.
Does Chrom Tech provide support beyond product sales?
Absolutely. Chrom Tech operates as a strategic distributor and solution partner, helping laboratories align instrumentation, pumping systems, and gas supply with long-term operational goals. Our consultative approach supports continuity planning, performance optimization, and reduced downtime.
How can upgrading instrumentation improve lab efficiency?
Modern pumps, degassers, and gas systems improve baseline stability, reduce maintenance frequency, and enhance method robustness. Chrom Tech helps laboratories evaluate upgrade paths that increase throughput while protecting analytical accuracy.
