Practical choices for routine analysis

7820AGas chromatography systems provide excellent gas chromatography analysis performance for all routine applications, including those that must comply with regulatory requirements.

Agilent 7820 GCKey Features:

1Equipped with an intuitive user interface and only five control buttons for the ammonium key, the gas path adjustment does not require the use of a pressure gauge or manual gas control knob. It is available in the system While improving overall performance, it also reduces the possibility of operational errors

2Use fully electronic gas path control on all injection ports and detectors(EPC)— Ensure better reproducibility of retention time and peak area, as well as reliable accuracy and precision.

3By setting the gas flow rate through software, you can save all important parameters of the analysis method. Digital circuits ensure that the set values between different operators are maintained during each operation*

4Standard high-precision injection port

1）Diversion/splitless(SSL)The injection port is suitable for large-diameter columns and all capillary chromatography columns

2）Filling column blowing injection port(PPIP)Suitable for large-diameter capillary columns and packed columns

5Automatic valve control

For the application in the petrochemical industry,7820AThe gas chromatography system can automatically control up to two heating valves

6Agilent's highly sensitive detectors are suitable for various samples

1）Flame ionization detector(FID)— The wide dynamic response range improves quantitative accuracy and is suitable for analyzing samples with high or low concentration components, reducing sample preparation requirements

2）Nitrogen and phosphorus detector(NPD)— For phosphorus or nitrogen-containing compounds, such as pesticide residues in food and environmental samples, it has excellent sensitivity and selectivity

3）Thermal conductivity detector(TCD)— Monofilament design provides lower noise and higher sensitivity for conventional analysis

4）Microcell electron capture detector(Micro-ECD)— Combining exceptional sensitivity, linearity, durability, and reliability

— If your laboratory analyzes halogenated organic compounds such as pesticides, polychlorinated biphenyls, and chlorinated solvents, this detector is your ideal choice

7, Used in conjunction withEZChrom Elite CompactSoftware that can be easily implemented in the laboratory7820AAll functions of gas chromatography system, this software is a fast and powerful chromatographic data system, including advanced data processing, flexible report editing, and all functions available from modern chromatographic workstations
