Heating and Cooling for Liquid Chromatography Systems

 Introduction

High-performance liquid chromatography (HPLC) is a technique used for analysis of liquid mixtures by separating, identifying, and quantifying their constituent components. Liquid chromatography normally operates with smaller amounts of material and seeks to measure the relative proportions of analytes in a mixture. R&D laboratories in the pharmaceutical, food science and oil industries use these instruments for product development or reverse engineering.

Common Coolant Types and their Uses in Liquid Cooling Systems

Introduction

As power densities and thermal loads continue to increase in crowded electronic systems, and specific analytical and diagnostic testing processes demand more temperature stabilization for improved accuracy and results, more equipment designers, R&D labs and diagnostic laboratories are turning to liquid cooling solutions for better thermal management. Optimal cooling fluids improve accuracy of results, improve equipment performance, minimize downtime, reduce maintenance costs, ensure safety and can help meet environmental compliance.

Thermal Management for Analytical Applications

Laird Thermal Systems offers a broad range of thermal management solutions delivering precise temperature control for laboratory equipment.
