GC Columns

Packed Columns

Packed columns are typically made of glass or metal tubing filled with a solid, inert support material coated with the stationary phase. They are generally wider and shorter than capillary columns, offering a higher sample capacity but lower resolution. They're often used for preparative-scale separations or for analysing simple gas mixtures.

Capillary Columns

Also known as open tubular columns, these are long, thin fused silica tubes with the stationary phase coated on the inner wall. Capillary columns offer superior resolution and sensitivity, making them ideal for separating complex mixtures. They are the most common type of GC column used in modern analytical labs.

Leading Supplier for GC Column & Customised GC Column in Singapore

Gas chromatography is undoubtedly one of the essential techniques for separating volatile compounds. It is helpful in the fields of health, medicine, drug analysis, food science, and more. It plays a crucial role in the fields of food and agriculture, industrial and environment, energy and chemical.

It therefore requires precision and infallible GC columns to ensure attested analysis.

At Shimadzu, we ensure our GC consumables span a broad range to suit your analytical needs. We provide GC columns, PLOT columns, and customised GC columns. Our GC column provides the best solution for most applications, giving reliable and reproducible results.

High-Quality Materials for Optimal Performance

Shimadzu prioritises quality and performance by carefully selecting premium-grade materials for our GC columns. We use materials with excellent thermal stability, low bleed characteristics, and high inertness, ensuring optimal column performance, minimising background interference, and maximising sensitivity for your capillary column GC applications. This allows for reduced limits of detection (LOD), quicker system stabilisation, and shortened conditioning times.

Versatile Applications for Diverse Needs

Shimadzu has a wide range of GC Columns available, including Fused Silica Capillary Columns, Fused Silica PLOT Columns, Stainless Steel Columns, Guard Columns, and application-specific columns. Whether you require analysis in pharmaceuticals, environmental testing, food and beverages, or materials science, our GC columns are designed to deliver accurate and precise results. Shimadzu GC columns are manufactured to the highest industry standard and designed to provide excellent chromatographic performance, reproducibility, and lifetime, complementing any GC/GC-MS instrument.

GC Guard Columns for Enhanced Protection

For enhanced performance and extended column life, Shimadzu also offers GC guard columns. These columns act as protective barriers, shielding the primary GC column by capturing contaminants or particles. By utilising a guard column, you can increase the lifespan of the GC column and save costs. 

Customised Solutions for Specific Requirements

Shimadzu understands that each GC column application is unique. That's why we offer customised columns tailored to your particular needs. Our team of experts will collaborate closely with you to understand your application and either recommend or develop a custom GC column that meets your precise specifications. 

For analytical challenges where standard columns fall short, we provide an array of specific columns for dedicated applications, including EPA methods, food analysis, and clinical samples. These columns have been rigorously tested to deliver optimal separation, precise quantification, and rapid analysis times.

For ultimate customisation, we offer bespoke services for gas chromatography columns. You can tailor the column to your specifications, choosing from glass or stainless-steel tubing and selecting the optimal diameter, length, solid support material, coated phase, and mesh size. By creating a custom GC column, you can enhance the performance and efficiency of your analyses.

Reliable GC Column Application at Shimadzu

GC columns and customised GC columns are the solutions to various applications. Shimadzu offers a wide range of high-quality GC columns, including capillary columns, metal columns, PLOT, and customised GC columns. We can provide you with dedicated capillary columns for GC used for pesticide analysis, analysis of fatty acid methyl esters (FAME) analysis, blood alcohol analysis, PCB analysis, volatile amine analysis and many other GC applications.

Metal Columns: Ideal for Specific Applications

Shimadzu's metal columns are specially designed for specific applications that require unique characteristics not found in traditional columns. Metal columns offer superior performance in applications such as sulphur compounds, permanent gases, and metal analyses. These GC columns provide excellent stability, robustness, and selectivity, enabling precise analysis of challenging samples in various industries.

PLOT Columns: Enhanced Separation for Complex Matrices

Our PLOT (Porous Layer Open Tubular) columns excel in analysing complex matrices and volatile compounds. The unique porous structure of PLOT columns allows for enhanced separation and analysis of typically difficult-to-resolve components. These columns are particularly suited for environmental analysis, forensic analysis, and volatile organic compounds (VOCs) analysis. PLOT columns offer superior retention capacity and can withstand challenging sample matrices, ensuring accurate and reliable results.

Selecting the Right GC Columns for the Best Performance

In order to obtain accurate and reliable results, consider the following factors when choosing a GC column:

Polarity: Match the polarity of the GC column to the polarity of your target compounds. A non-polar column is best for non-polar compounds, while a strongly polar column is needed for polar compounds.

Objective: For compounds with a large difference in boiling points, a non-polar column works best. For isomers or compounds with very similar boiling points, a strongly polar column is necessary to achieve adequate separation.

Resolution and Speed: A long, thin column offers high-resolution separation but takes more time. For faster analysis with adequate separation, use a shorter, thicker column with a thinner coating.

Compounds: For low-boiling-point compounds, use a long column with a thick coating. For high-boiling-point compounds, a short column with a thin coating is more suitable.

Frequently Asked Questions about GC Columns

What is the difference between GC and HPLC columns?

GC columns are used in gas chromatography to separate volatile compounds based on their boiling points, while HPLC columns are used in liquid chromatography to separate compounds dissolved in a liquid mobile phase.

Are GC Columns polar?

GC columns can be non-polar, mid-polar, or polar. The choice of polarity depends on the analytes you are separating, as the principle of separation is based on the interaction between the compounds and the column's stationary phase.
