Precision and efficiency reign supreme in Gas Chromatography (GC), and PLOT (Porous Layer Open Tubular) columns are indispensable tools to attain these objectives. 

Gas Chromatography, often abbreviated as GC, involves the separation of chemical compounds within a gaseous mixture based on their differing affinities to a stationary phase and a mobile phase. ShopShimadzu, a renowned name in analytical and measuring instruments, as well as medical systems, since its inception in 1989, offers a comprehensive range of PLOT (Porous Layer Open Tubular) columns through ShopShimadzu. With their specialised porous layer design, these columns play a pivotal role in enhancing the precision and efficiency of gas chromatography analyses.

ShopShimadzu’s commitment to excellence is evident in its PLOT column offerings, tailored to meet diverse analytical needs. ShopShimadzu promises precision and efficiency in gas chromatography with the right PLOT columns, ensuring accurate and reliable results for analytical professionals.

Choosing the Right PLOT Column

When selecting the ideal PLOT column to meet your specific GC needs, ShopShimadzu offers a comprehensive range of options prioritising precision and efficiency. Here are some of the key technical features of ShopShimadzu’s PLOT column to keep in mind: 

  • Column Material: When choosing a PLOT column, selecting column material is crucial. Materials like alumina, silica, and molecular sieves are available, each with unique compatibility profiles. Alumina is ideal for polar analytes, silica for nonpolar compounds, and molecular sieves for selective adsorption. Make your choice wisely to ensure precision in your gas chromatography analysis.
  • Column Dimensions: Consider the inner diameter, length, and film thickness when selecting a PLOT column. Longer columns enhance separation but require more time. Thicker films provide improved capacity but might require higher carrier gas flow rates. Choose longer or wider PLOT columns based on your specific analysis requirements for optimal gas chromatography performance.
  • Temperature Stability: Temperature stability is critical for consistent gas chromatography results. High-temperature PLOT columns excel in maintaining precision. Choose these columns for applications demanding elevated temperatures, such as petrochemical analysis. Alumina-based PLOT columns are ideal for high-temperature applications, ensuring reliable and accurate GC analyses.
  • Application Specificity: Customise PLOT GC columns for distinct analytical needs like hydrocarbon analysis or environmental monitoring. Select columns based on targeted compounds, such as molecular sieves for hydrocarbons. Adjust dimensions for enhanced sensitivity. Tailoring PLOT columns ensures precise results, making them perfect for unique analytical requirements, from environmental compliance to hydrocarbon quantification.


PLOT Columns vs Other GC Column Types

ShopShimadzu’s PLOT columns exhibit a distinct design, featuring a porous structure for enhanced selectivity, setting them apart from other GC column types. This unique attribute ensures precise separation and quantification of compounds in gas chromatography applications. Here's a comparison:

  • PLOT Column vs HPLC Column: PLOT columns and High-Performance Liquid Chromatography (HPLC) columns serve distinct purposes. PLOT columns excel in gas chromatography, focusing on gaseous samples. HPLC columns, on the other hand, cater to liquid-phase separations. The critical difference lies in their utility: PLOT columns deliver precise results for gaseous analytes, while HPLC columns are ideal for liquid samples.
  • PLOT Column vs Packed Column: A fundamental distinction lies in their operational functions and requirements when comparing PLOT and packed columns. PLOT columns shine in this regard due to their open tubular design. This eliminates the necessity for meticulous packing, which can introduce inconsistencies. However, they are more fragile and may require temperature programming. Custom packed columns demand precise packing, rendering them more susceptible to operational variations. These columns run isothermally and have a more rugged nature, allowing more flexibility and faster run time.
  • PLOT Column vs GC Column: Comparing PLOT columns with conventional GC columns exposes a notable distinction: PLOT columns feature a distinctive porous structure that elevates selectivity and sensitivity. While both excel in gas-phase analysis, PLOT columns showcase exceptional separation capabilities, especially for permanent gases, thanks to their specialised design. The decision between these two options hinges on the precise analytical prerequisites and the nature of the compounds under examination.


Advantages of PLOT Columns in Gas Chromatography

When it comes to gas chromatography, PLOT columns bring several distinct advantages to the table:

  • Enhanced Selectivity and Sensitivity: PLOT columns are renowned for their remarkable selectivity and sensitivity. Their unique design ensures precise compound separations and quantification, making them the go-to choice for analytical professionals seeking the utmost precision in their results. Whether dealing with complex mixtures or trace-level analysis, PLOT columns consistently deliver superior sensitivity and selectivity.
  • Improved Separation of Permanent Gases: One of the standout features of PLOT columns is their exceptional ability to separate permanent gases effectively. The porous structure within PLOT columns enhances the separation of these gases, even in the most challenging analytical applications. This capability is particularly advantageous when working with samples containing permanent gases, such as nitrogen or carbon dioxide, ensuring the accuracy and reliability of GC analyses.
  • Low Sample Volume Requirements: Efficiency is a hallmark of PLOT columns. They excel in delivering accurate results while requiring smaller sample volumes. This efficiency can be a game-changer, especially when dealing with limited or valuable samples. By minimising sample consumption, PLOT columns save resources and enable thorough analyses, even when sample availability is restricted.
