Products Company PASR Conference Support Contacts


It is difficult to determine the exact date of our company creation. It was formed in the beginning of the 90th on the basis of VNIIFTRY Laboratory of spectrometry and radiometry as an independent group for software development and methodological maintenance of the ionizing radiation spectrometry. For a time the group was a part of Expertcenter, then a part of the SPC Doza. Finally, independent firm LLP LSRM was registered in 1994. It was re-registered to OOO LSRM in 1997.

The first commercial products of our company are the gamma-spectra processing software PPD-02, Sc-92. They were developed in 1992 under LSRM brand even before the firm obtained the official status. We were the first company in CIS and nearly all over the world who created the professional software of the spectrometry measurements for Windows environment. After that the firm became the leader of the radiation monitoring software development.

SPC Aspect has been the closest partner of LSRM for years. Our software always supported all analyzers and analyzer cards of SPC Aspect. Since 1998 SPC Aspect has accepted the "Lsrm for Windows" software package as a basic one for its spectrometer devices. It was a great step to move on a new level of our relationships. LSRM became the participant in SPC Aspect spectrometry developments. In turn, our software passed careful testing in SPC Aspect departments. So algorithms and methodologies developed in LSRM are used in portable Gamma-1C/NB, MKS-A02 spectrometers. One of the significant team developments was the LsrmCustoms software for Gamma-1C/NB spectrometers under orders of the State Customs Committee.

Nowadays our software has been adapted for the different types of detectors (for gamma radiation with HPGe, NaI, CsI, LaBr3(CI3), CdZnTe) and for detectors from different manufactures: SPC Aspect, BSI, Ortec, GBS Electronik, Canberra, XIA, IFTP, Atomtex, STC Amplituda, OAO Expertcenter, SPC Doza. BSI includes our software into the complete set for its spectrometry hardware.
