Questions answered in these manuals
What are the power requirements for the Agilent 6820?
The system supports voltages of 120 V, 200 V, 220 V, 230 V, and 240 V with a frequency range of 47.5~63 Hz.
Which detectors are available for the 6820 system?
Available detectors include Flame ionization detector (FID), Thermal conductivity detector (TCD), Electron capture detector (ECD), and Nitrogen phosphorous detector (NPD).
Which detector is used in this application method?
The method uses a flame ionization detector (FID), which is noted as easier to maintain than the thermal conductivity detector (TCD) used in the standard ASTM D3606.
What software is used for control and data analysis?
Agilent Cerity NDS software is used for 6820 GC control and data analysis.
What compounds are determined by this method?
The specific compounds determined include methyl tert-butylether (MTBE), ethyl tert-butylether (ETBE), tert-amylmethylether (TAME), diisopropylether (DIPE), and various alcohols such as methanol, ethanol, and propanol.
What is the recommended backflush time for analyzing DIPE?
For this system, a backflush time of 0.22 minutes is used for the analysis of DIPE to ensure hydrocarbons are completely eluted while ethers are retained.
