Are you struggling to source reliable liquid chromatography consumables in bulk without risking system performance or test accuracy?
Do you worry about inconsistent quality, long lead times, or poor compatibility with your Agilent, Waters, or Shimadzu LC systems?
Are you unsure which materials or specifications are truly suitable for your solvents, pressure levels, and applications?
Liquid chromatography consumables play a critical role in analytical testing. They directly affect efficiency, cost control, safety, and data reliability in laboratories and production environments.
Liquid Chromatography (LC) is a widely used analytical technique for separating, identifying, and quantifying compounds in liquid samples (see definition on Wikipedia). From pharmaceuticals and food safety to environmental monitoring, LC systems depend on stable, high-quality consumables to operate correctly.
In this article, you will learn how to understand LC consumables, evaluate quality standards, source in bulk efficiently, and why Chromasir is a trusted global supplier for liquid chromatography consumables.
Understanding Liquid Chromatography Consumables: The Foundation for Sourcing
Key Technical Specifications
Common Materials and Their Advantages
316L Stainless Steel
High strength, corrosion resistance, and pressure tolerance. Ideal for UHPLC systems and organic solvents.
PEEK (Polyether Ether Ketone)
Excellent chemical resistance and biocompatibility. Commonly used in bioanalysis and metal-sensitive applications.
PEEK-lined Stainless Steel
Combines pressure strength with low metal interaction.
Titanium (selected components)
Suitable for high-salt buffers and aggressive mobile phases.
Design Types and Structures
Capillaries (straight, coiled, pre-cut lengths)
Fingertight and tool-assisted fittings
Check valve cartridges (ruby or ceramic)
Inline solvent filters and sample loops
Each structure is designed for specific pressure levels, flow rates, and system layouts.
Standard and Custom Sizes
Standard tubing sizes: 1/16″ and 1/8″
Common inner diameters: 0.1 mm – 0.5 mm
Custom lengths and diameters available for OEM and special applications
Standard sizes ensure compatibility, while custom designs improve performance for specific workflows.
Additional Design Considerations
Electropolished inner surfaces for reduced adsorption
Low-dead-volume connections
Leak-resistant threading designs
These details strongly impact baseline stability and system lifespan.

For example, Chromasir capillaries are used in continuous environmental water monitoring projects running over 200 hours with stable pressure and repeatable results.
Essential Quality and Compliance Standards
Required Certifications
ISO 9001:2015 quality management system
RoHS and REACH compliance (material-based)
Quality Inspection Process
Incoming raw material inspection
In-process dimensional control
Pressure and leakage testing
Functional performance testing
Final cleaning, labeling, and batch traceability
These steps ensure consistent quality for bulk orders.
