The Future of Chromatography Consumables & Solutions in Laboratory Services

Chromatography is one of the most widely used analytical techniques in laboratory testing today. As laboratories continue to develop more advanced capabilities, the future of chromatography consumables and solutions looks bright. This article explores emerging trends and innovations that will shape chromatography practices in the years ahead.

An Overview of Chromatography

Chromatography encompasses a broad range of laboratory techniques used to separate the components of a mixture for further analysis. The core principle involves a mobile phase and a stationary phase - the components in the sample mixture move at different rates through the stationary phase and get separated into distinct bands.

The sample mixture is introduced into the system - either a liquid or gas mobile phase - and flows through the stationary phase contained in a column - typically a glass or metal tube. The differential migration happens due to the unique chemical interactions of each sample component with the stationary phase. The separated bands then flow out of the column where they are analyzed by a detector. The signal produced is amplified and converted into a chromatogram that can be analyzed. The time taken from injection to detection is called the retention time, which serves as a unique identifier for each analyte.

Some commonly used chromatography techniques are:

• High-performance liquid chromatography (HPLC): A versatile, robust technique using a liquid mobile phase. Widely used across many industries. Different modes like reverse-phase, normal phase, ion exchange etc. are possible based on the chemistry of the stationary phase.
• Gas chromatography (GC): Ideal for volatile and thermally stable compounds using an inert gas as the mobile phase.
• Ion chromatography (IC): Separation based on ionic interactions. Commonly used for ionic species and polar compounds.
• Size-exclusion chromatography (SEC): Separates analytes based on size. Larger molecules elute faster than smaller ones. Ideal for polymers, proteins, oligonucleotides etc.
• Affinity chromatography: Utilizes a stationary phase with immobilized ligands that have specific binding affinity for the analyte molecules. Highly selective purification possible.
• Supercritical fluid chromatography (SFC): Employs supercritical fluids like supercritical carbon dioxide as the mobile phase. Combines advantages of GC and LC.
• Thin-layer chromatography (TLC): A simple, low-cost technique using thin stationary phase layered on a glass or plastic plate. Widely used for preliminary testing.

In addition to these, more advanced hyphenated techniques like LC-MS, GC-MS, LC-NMR etc. that combine separation with spectroscopic detection are becoming popular as they add another layer of selectivity and sensitivity.

Chromatography finds extensive use across pharmaceuticals, biotechnology, food testing, agriculture, environmental analysis, petrochemicals, forensics, academic research and many other domains. It allows identification and quantification of specific analytes within complex sample matrices. Chromatography generates reliable, sensitive, and reproducible data that aids further confirmatory analysis and decision making.

The Growing Importance of Chromatography

Modern chromatography has become an indispensable tool in contemporary laboratories due to its unique advantages:

• Extremely high sensitivity and accuracy: Cutting-edge chromatography systems offer detection limits going down to pictograms and excellent accuracy. This allows accurate detection and quantitation of minute levels of analytes.
• High reproducibility: Automated systems with advanced columns and optimized methods result in very high reproducibility. This reliability is critical for stringent quality testing requirements.
• Broad applicability: Chromatography can analyze a vast range of compounds from small molecules to proteins, polymers, lipids etc. in gaseous, liquid or supercritical fluid mobile phases. This versatility supports usage across diverse verticals.
• Multi-analyte analysis: A single run can separate and analyze multiple components in a sample. This supports efficient, high-throughput analysis.
• Hyphenation with other techniques: Coupling chromatography with spectroscopic techniques like mass spectrometry or NMR generates very valuable data otherwise not possible from individual techniques.
• Compliance with regulatory standards: Validated chromatography methods adhering to cGMP, USP, ICH etc. guidelines are necessary for accredited facilities in pharmaceuticals, healthcare, food testing etc.
• Automation capabilities: Autosamplers, optimization software, automated data analysis etc. make chromatography efficient and compliant.

Considering these advantages, chromatography has become vital for contemporary lab testing processes and this importance will only grow in the future driven by crucial industry megatrends.

Key Chromatography Consumables

To perform chromatography, laboratories need a wide range of high-quality consumables and accessories. Choosing validated products from reputed vendors is critical as substandard consumables can adversely affect the separation and end results.

• Narrow-bore columns with smaller diameters like 2.1 mm x 100 mm for reduced solvent usage.
• Short columns for rapid separations. 30-50 mm length.
• Microbore columns less than 1 mm diameter for capillary chromatography.
• Preparative columns with large diameters for isolation and purification. Example - 50 mm x 300 mm.
• Guard columns to protect the main column. Installed before the primary column.
• Reversed-phase columns containing non-polar stationary phases like C8, C18. Most common type.
• Normal phase columns with polar stationary phases like silica.
• Ion exchange columns for separation by ionic interactions. Anion or cation types possible.

Solvent filtration is mandatory before use:

• Membrane disk filters (0.2 - 0.45 μm) for bulk solvent filtration at lab level.
• Syringe-tip filters for small volume filtration before analysis.
• In-line solvent filters to filter continuously online. Protect columns.
• Vacuum filtration systems for batch filtration. Fast filtration of bulk volumes.
  
  

Accessories

Additional key accessories include:

• Syringes and needles for manual injection. Agilent, Hamilton, Thermo, etc. offer chromatography-specific products.

• Certified reference standards - Solutions of high purity compounds for calibration and QC.
• Ferrules and nuts - PEEK, stainless steel, titanium - finger tight or advanced designs.
• Sample loops/O-rings - For injectors. Range 1 μL - 5 mL.
• Crimpers, decappers, rackers, wash stations - for productivity.
• Vial inserts - Reduce volume for limited sample amounts.

Thus, laboratories must procure a wide variety of optimal consumables to support diverse chromatography applications while maintaining quality and throughput.
