In the realm of analytical chemistry, precision and reliability are non-negotiable. Chromatographic techniques, such as Gas Chromatography (GC), are indispensable tools for separating, identifying, and quantifying chemical compounds. The accuracy of these analyses hinges on the quality of the standards used for calibration. Tetradecane (CAS 629-59-4), a well-characterized saturated hydrocarbon, stands out as a valuable standard for chromatographic analysis due to its stable properties and high purity.

Why Tetradecane is Ideal for Chromatography
Tetradecane is a colorless liquid with the molecular formula C14H30. Its significance in chromatography stems from several key attributes:

  • Defined Molecular Structure: As a pure alkane, Tetradecane has a straightforward and predictable chemical structure. This leads to a consistent retention time in chromatographic systems.
  • High Purity: Typically available at 99.5% purity, it minimizes interference from impurities that could skew analytical results. This high purity is crucial for calibrating instruments and validating analytical methods.
  • Chemical Inertness: Its saturated nature makes Tetradecane relatively inert, meaning it does not readily react with the stationary phase of the chromatography column or with other components in the sample matrix.
  • Suitable Boiling Point: With a boiling point around 254°C, it is suitable for use in GC, allowing for separation and detection without decomposition.

Using Tetradecane as a Standard
Chromatographic analysis often involves comparing an unknown sample to known standards. Tetradecane can be used in several ways:

  • Calibration Standard: It can be used to calibrate detectors or to establish a retention time window for similar hydrocarbon compounds.
  • Internal Standard: In quantitative analysis, Tetradecane can be added in a known concentration to both standards and samples. This helps to compensate for variations in injection volume or detector response, leading to more accurate results.
  • Method Development: R&D scientists may use Tetradecane to test and optimize the performance of new chromatographic columns or methods.

Sourcing High-Quality Tetradecane for Laboratories
For laboratories and research institutions, procuring Tetradecane that meets stringent purity requirements is vital. When seeking to buy Tetradecane for chromatographic applications, it is advisable to partner with reputable chemical suppliers who can guarantee the purity (e.g., 99.5%) and provide essential documentation such as Safety Data Sheets (SDS) and Certificates of Analysis (CoA). Comparing prices and ensuring consistent availability from a trusted manufacturer is also important for laboratory operations.

Ensure the accuracy of your chemical analyses by using high-purity Tetradecane as your chromatographic standard. Inquire with reliable suppliers for the best quality and pricing.
