Summary

**Summary:** This is an instrument control parameter file for an **Agilent GC 8860 – 5977B MSD** system (Gas Chromatography-Mass Spectrometry), generated on **February 22, 2024**. The method file (`CatTestMethod01.M`) appears designed for **catalysis research** (as indicated by the method name), likely for analyzing reaction products or feedstock mixtures. **Key Parameters:** - **GC Configuration:** HP-5ms Ultra Inert column (30 m × 250 μm × 0.25 μm) with helium carrier gas (1 mL/min, constant flow). Oven program: 50°C (2.25 min) → 240°C at 40°C/min (1 min hold), total run time 8 min. - **Injection:** Front ALS (Automatic Liquid Sampler), 1 μL injection volume, **split mode** (100:1 ratio, 250°C inlet temperature). - **MS Acquisition:** **Scan mode** over **m/z 50–550**, solvent delay 2.1 min, electron ionization (EI) source at 230°C, quadrupole at 150°C. - **Tune Parameters:** Includes specific voltage settings for the MS source (emission current, repeller, ion focus, etc.) and electron multiplier (EM) voltage (~936 V). **Context:** The file represents a standard analytical method for separating and detecting organic compounds (likely catalytic reaction products) using a non-polar capillary column with mass spectrometric detection.

Title
GC-MS Method Parameters: CatTestMethod01
Description
Instrument control parameter file for an Agilent GC 8860 – 5977B MSD system (Gas Chromatography-Mass Spectrometry), generated on February 22, 2024. The method file (CatTestMethod01.M) is designed for catalysis research, configuring the separation and detection of organic compounds (likely catalytic reaction products or feedstock mixtures) using a HP-5ms Ultra Inert capillary column with helium carrier gas and electron ionization mass spectrometry in scan mode (m/z 50–550).
