Matrix ICMS provides a convenient method of maintaining records of all equipment on a company site. Originally designed for laboratory equipment applications the latest version is now suitable for all equipment and devices that require records of calibration and maintenance. The system holds and reports on three classes of important information — instrument inventory, instrument calibration and instrument maintenance. It can schedule calibration and maintenance intervals and issue reminders when the next action is needed. When used with the Matrix LIMS it can ensure that only valid instruments are scheduled for testing. The latest version also includes records of electrical safety checking. In addition, an instrument system (e.g. HPLC) can be linked to components (e.g. detector, pump, etc) which can be individually managed.
