Sulfur Chemiluminescence Detector

The reimagined and redesigned Agilent 8355 SCD represents the first major advance in sulfur chemiluminescence detection in 25 years, making the technology more reliable and easier to use. Highly sensitive and highly specific, the reimagined detector is also easier to maintain, thanks to a simplified burner design with 50 percent fewer components. The most common service routine, which used to take one hour, now takes only 10 minutes. The 8355 employs a dual plasma burner to achieve high temperature combustion of sulfur-containing compounds to form sulfur monoxide (SO). A photomultiplier tube detects the light produced by the chemiluminescent reaction of SO with ozone. This results in a linear and equimolar response to the sulfur compounds, without interference from most sample matrices.

1 MDL: Burner temperature 800 °C, 8 mL/min lower hydrogen, 38 mL/m upper hydrogen, 50 mL/min air,
tert-butyl disulfide in SCD checkout sample (5190-7003) as the test compound, 30 m × 0.32 mm, 1 µm
DB1 (123-1033), 50 °C for 3 minutes, 25 °C/min to 160 °C, hold 2 minutes, 1 µL splitless injection, fully
stabilized burner.
2 Selectivity: Defined as the sensitivity of S over the sensitivity of a selected hydrocarbon. Operating
parameters same as MDL. Isooctane (sample solvent) and tert-butyl disulfide in the SCD checkout
sample are used as the testing compounds. Selectivity performed on a fully stabilized burner.
3 Linearity: Operating parameters same as MDL except 12 mL/min lower hydrogen and
38 mL/m upper hydrogen; 80 °C for 1 minute, 25 °C/min to 160 °C, hold 2 minutes, COC inlet;
Test compound: tert-butyl disulfide in isooctane. Linearity performed on a fully stabilized burner.
4 SCD specifications apply only when using air as the oxidizer gas.

    Difference in calibration standard result

    I calibrated an SCD-GC with a 1 ppmW total sulfur in Helium matrix balance but noticed wide difference in the result of a known certified standard (1 ppmW total sulfur in methane matrix)when analyzed on the SCD-GC.
