When did your analytical instruments have a maintenance inspection?

Regular maintenance of your instrumentation retains accuracy and prolongs its productivity; when is your next inspection due?




Maintenance is the vital quality assurance step in any analytical process that justifies the accuracy of results from an instrumentation perspective. Without regular maintenance, results may still be reliable however there is greater potential for systemic errors to go unnoticed during extended use of equipment. Abrasion, deformation, mechanical and thermal fatigue, and other routes of failure, are difficult to detect unless a system-wide inspection is performed. During this process each component is closely examined and individually authenticated to ensure accurate operation of the system as a whole.

IQ-OQDuring the inspection it is also possible to identify areas subject to greater wear and to provide additional training for the operators on improved handling methods. This can ultimately help to reduce instrument degradation resulting in better quality of use and efficiency improvements, and a higher throughput of samples. Depending on the extent and regularity of use, and the demands placed on the equipment, we can also advise as to how regularly maintenance should be performed to ensure system downtime is kept to a minimum.

Cleaning should be performed between samples and at the end of each day’s analysis, removing the contaminants with cleaning liquid, a small amount of solvent and deionized water before being air-dried. Over time, contaminant build-up from ineffective cleaning can damage sensitive probes and the analysis platform, with the deterioration being difficult to observe. Cumulative system damage is easily identified by our highly trained engineers.

It is recommended to have the system revalidated annually for normal use, however the regulatory requirements of your industry and any internal requirements might warrant maintenance and validation at an increased frequency. Some facilities may require up to monthly validation to reduce the potential for errors and to ensure any data is correct and that the instrument is working within specification.
