About This Presentation
Title:

The Role of Capillary Columns in Gas Chromatography: Separating Compounds with Precision

Description:

The sample is injected into the GC column at the inlet end. The carrier gas (usually helium) carries the sample through the column. The sample compounds interact with the stationary phase and are separated based on their boiling points. The compounds with the lowest boiling points will elute from the column first, followed by the compounds with the highest boiling points. – PowerPoint PPT presentation

    Chromatography Separating Compounds with
    Precision
  • The detector at the outlet end of the column
    detects the eluted compounds and produces a
    signal that is proportional to the amount of
    each compound. The signal is then processed by
    the GC data system and a chromatogram is
    produced. The chromatogram shows the peaks of
    the eluted compounds, which can be used to
    identify and quantify the compounds.
  • Capillary columns are used in a wide range of
    applications, including
  • Environmental analysis Capillary columns are
    used to analyze air, water, and soil samples for
    a variety of pollutants, including volatile
    organic compounds (VOCs), pesticides, and
    herbicides.
  • Food and beverage analysis Capillary columns are
    used to analyze food and beverage samples for a
    variety of compounds, including flavor
    compounds, aromas, and contaminants.
  • Pharmaceutical analysis Capillary columns are
    used to analyze pharmaceutical products for
    purity and potency.
  • Industrial analysis Capillary columns are used
    to analyze industrial products for a variety of
    compounds, including quality control and process
    monitoring.
  • Zero Air Generators for Gas Chromatography
  • A Zero Air Generator for Gas Chromatography is a
    device that produces high-purity air that is
    free of contaminants. Zero air generators are
    used in gas chromatography to provide a clean
    carrier

gas for the sample.

  • Zero air generators work by passing compressed
    air through a series of filters and scrubbers.
    The filters and scrubbers remove contaminants
    from the air, such as moisture, carbon dioxide,
    and hydrocarbons. The resulting zero air is then
    used as the carrier gas for the GC column.
  • PID Analyzers
  • A photoionization detector (PID) analyzer is a
    type of gas detector that uses photoionization
    to detect volatile organic compounds (VOCs). PID
    analyzers work by irradiating the sample gas with
    ultraviolet (UV) light. The UV light ionizes the
    VOC molecules, which produces a signal that is
    proportional to the amount of VOCs in the sample
    gas.
  • PID analyzers are used in a wide range of
    applications, including
  • Environmental monitoring PID analyzers are used
    to monitor air quality for VOCs.
  • Industrial hygiene PID analyzers are used to
    monitor for VOCs in the workplace.
  • Leak detection PID analyzers are used to detect
    leaks of VOCs from pipelines and other
    equipment.
  • Scientific Gas Generator Systems Suppliers
  • Scientific gas generator systems suppliers
    provide a wide range of gas generators for gas
    chromatography and other analytical applications.
    These suppliers offer a variety of different
    types of gas generators, including zero air
    generators, hydrogen generators, and nitrogen

generators.

  • When choosing a scientific gas generator system
    supplier, it is important to consider the
    following factors
  • The type of gas generator you need Make sure
    that the supplier offers the type of gas
    generator that you need for your application.
  • The purity of the gas Consider the purity of the
    gas that you need for your application. Some
    applications require high-purity gas, while
    others can tolerate lower purity gas.
  • The flow rate Consider the flow rate of gas that
    you need for your application. Some applications
    require a high flow rate of gas, while others
    can tolerate a lower flow rate.
  • The price Compare the prices of different gas
    generators from different suppliers.
  • GC Column Manufacturers
  • GC column manufacturers offer a wide range of
    capillary columns for different applications.
    When choosing a GC column, it is important to
    consider the following factors
  • The type of stationary phase The type of
    stationary phase will affect the separation of
    the sample compounds.
  • The length and diameter of the column The
    length and diameter of the column will affect
    the resolution and separation time.
