Shimadzu Scientific Instruments’ ECD-2010 Exceed electron capture detector (ECD) features a newly designed capillary ECD cell with Shimadzu’s contact-free technology to reduce the effect that a dirty sample matrix can have on the detector’s radioactive source. This allows the ECD-2100 to perform gas chromatography testing on samples such as polychlorinated biphenyl analysis in soil or analyze other difficult matrices. The design uses a sweep gas to minimize contact of the sample with the detector source during the detection process.
