Title: The Role of Capillary Columns in Gas Chromatography: Separating Compounds with Precision
1- QUADREX CORPORATION
- The Role of Capillary Columns in Gas
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.
