Agilent 6890N Network GC System

Agilent 6890N Network GC System

Agilent 6890N Gas Chromatograph (GC) is a reliable and widely used GC model, known for its robust performance and precision. Although it’s an older model compared to newer Agilent GCs, the 6890N remains popular in many laboratories for its dependable analytical capabilities, particularly in routine and high-throughput applications.

Key Features

Electronic Pneumatic Control (EPC): Provides precise and consistent control of carrier gas flow and pressure, enhancing reproducibility and accuracy across runs.

Versatile Detector Options: Compatible with various detectors, such as Flame Ionization Detector (FID), Electron Capture Detector (ECD), Thermal Conductivity Detector (TCD), and Nitrogen-Phosphorus Detector (NPD), allowing it to handle a broad range of analytes.

Temperature Programming and Precision: Features precise temperature control, with rapid oven cooling and programmable temperature options to support complex, multi-analyte separations.

Split/Splitless and Capillary Inlet Options: These injection port configurations accommodate different sample types and injection volumes, making the 6890N flexible for various applications.

Automated Sampling: Compatible with autosamplers like the Agilent 7683 or other compatible models, enabling high-throughput and automated sampling to improve workflow efficiency.

Data Acquisition and Software: Often paired with Agilent’s ChemStation software, which provides control, data acquisition, and analysis functions for streamlined operation.

Applications of the Agilent 6890N

The 6890N is well-suited for:

Environmental Testing: Detection of pesticides, volatile organic compounds (VOCs), and semi-volatile compounds in water, soil, and air samples.

Food and Beverage Analysis: Analysis of contaminants, additives, and flavors in food and beverage matrices.

Pharmaceutical and Chemical Analysis: Used in quality control and stability testing, as well as for impurities and residual solvent analysis.

Petroleum and Petrochemical Testing: Characterization of hydrocarbons, as well as the detection of sulfur and other trace contaminants in fuels.

Why Labs Still Use the Agilent 6890N

While Agilent has since developed more advanced GC models (like the 7890 and 8890 series), the 6890N remains valued in labs for its robustness and reliability. It’s a highly dependable choice for labs with established methods and protocols, particularly those that require a cost-effective, routine-use GC solution.
