Selecting the Ideal Chromatography Consumables & Solutions Provider

‍Chromatography is a crucial analytical technique used in laboratories across industries to separate, identify, and quantify components in a mixture. The quality of your chromatography results depends heavily on using the right consumables and solutions. Choosing the ideal chromatography consumables and solutions provider is key to ensuring accurate, reproducible results from your chromatographic analyses.

Key Considerations When Selecting a Chromatography Consumables & Solutions Provider

Selecting the right chromatography consumables and solutions provider is a crucial decision that impacts the quality of your analytical results. Carefully evaluate potential vendors against the following key criteria:

Quality and Consistency of Products

Chromatography columns, vials, solvents, standards, and accessories must be manufactured consistently to the highest quality standards. Even minor variations in product quality can negatively affect separation efficiency, resolution, and reproducibility. Rigorously examine a supplier's quality control procedures, ISO certifications, regulatory compliance, lot testing data, and overall commitment to excellence. Tour their production facilities if possible to observe first-hand. Avoid vendors with quality lapses or frequent complaints about defective products.

‍

Depth of Product Portfolio

Seek out providers that offer an extensive range of chromatography supplies for your technique, rather than a narrow specialty. For example, leading HPLC consumables suppliers will offer columns with diverse stationary phase chemistries (C18, C8, ion exchange, chiral, etc.), vials, mobile phases, standards, filters, autosampler parts, and accessories. This enables one-stop shopping and ensures all products are designed to work together optimally.

Key Types of Chromatography Consumables and Solutions

Successfully performing chromatographic separations and analyses requires the right mix of high-quality consumable products and solutions. When selecting a consumables provider, ensure they offer a comprehensive range of chromatography supplies spanning:

HPLC Columns

The column is the heart of high performance liquid chromatography. Various stationary phases separate analytes based on polarity, charge, size, or chirality. Common phases include:

• Reverse Phase – Uses non-polar C18 or C8 bonded silica. Most widely used for separating non-polar to moderately polar compounds.
• Normal Phase – Polar stationary phase like silica or alumina for separating non-polar and polar compounds.
• Ion Exchange – Charged stationary phases separate ionic/ionic compounds and biomolecules based on charge.
• Size Exclusion – Porous particles separate by molecular size, ideal for polymers and large molecules.
• Chiral – Contains chiral selectors that separate enantiomeric compounds.

GC Columns

‍Gas chromatography depends on capillary columns coated with liquid stationary phases. Common phase chemistries include:

• 5% Phenyl Polysilphenylene-siloxane – Ideal for a wide range of organic compounds from C3 to C28+.
• 100% Dimethylpolysiloxane – Most popular and versatile GC phase for non-polar analytes. Stable up to 380°C.
• Wax phases – Polar wax-like phases for alcohols, acids, amines.
• Ionic liquids – Polar ionic liquid coatings for polar analytes, thermal stability up to 400°C.

Sample Vials

Autosampler vials contain samples for automated injection. Options:

• Glass vials – Inert with good solvent compatibility. Available in clear or amber.
• Polypropylene vials – Durable plastic vials resistant to breakage. Autoclavable.
• Threaded vials – Screw caps ensure secure closure.
• Crimp top vials – Aluminum caps crimped onto vials. Offer leak-proof sealing.

Mobile Phases

Mobile phases carry samples through the chromatography column. Key components:

• Water – Universal weak mobile phase component. Deionized water avoids interference.
• Organic solvents – Acetonitrile, methanol etc. adjust eluent strength. Miscible with water.
• Buffers – Phosphates, acetates, etc. control pH and ionic interactions.
• Ion pairing reagents – Enhance retention of ionic analytes. Common choices are TFA and HCOONH4.

Standards and Reagents

‍
Standards enable analyte identification and quantification:

• Individual standards – Single component references for specific analytes.
• Standard mixes – Combinations of standards for multi-analyte analysis.
• Internal standards – Spiked into samples to correct for errors.

Reagents like salts and buffers prepare samples and mobile phases.

Filtration Supplies

Membrane syringe filters and discs remove particles that damage columns:

• Syringe filters – Simple filtration using Luer-lock syringes.
• Filter discs – Larger volumes with reusable filtration units.
• Membrane materials – Nylon, PTFE, PVDF, regenerated cellulose.
• Pore sizes – 0.2 μm up to 1.5 μm for coarse filtration.

Vial Caps and Septa

Caps and septa secure chromatography samples and standards:

• Screw caps – Plastic caps thread onto vials. Eliminate need to crimp.
• Crimp caps – Leak proof seal from aluminum cap pressed onto vial.
• Septa – Silicone, PTFE or rubber liners in cap for needle penetration.

Autosampler Supplies

Autosamplers require replacement of wear parts:

• Sample syringes – Precision syringes that must be changed periodically.
• Needles – Stainless steel needles for consistent injection volumes.
• Loop inserts – Fixed volume sample loops for metering injections.
• Rheodyne valves – Valves and rotor seals for controlling sample flow.

This overview provides a solid foundation for evaluating the breadth and depth of a supplier's chromatography consumables selection.
