Multi-gas GC analyzer for trace analysis

Since 2018, the company LDETEK is an integral part of Process Sensing Technologys.
Through its 7 brands including Michell Instruments, AII, NTRON, ROTRONIC, the PST Group has established itself as a leader in online moisture and oxygen analysis technologies.
This acquisition strengthens the group’s solution portfolio by bringing an innovative and powerful solution for trace analysis.
Pioneer in the use of the Plasmadetek detector, (PED plasma emission detector), Ldetek has developed a unique analytical solution for the characterization of impurities in pure gases (He, Ar, H2…) but also in complex matrices.
The LDTEK range is based around a Multidetek2 modular chromatographic platform (which can integrate a wide range of detectors, PED, TCD, FID…). It also includes a range of on-line analyzers for the characterization of impurities in pure gases (LD8000, LD8000 Multi-gas, LD2000).
The performance and specifications of Ldetek’s products and Chemlys’ expertise in these technologies favored the rapprochement between the two companies.
Today, the partnership between Chemlys and PST France is the assurance of a relevant answer and in complete adequacy with the expectations of the addressed markets.
