The charged aerosol detector (CAD) is a detector used in conjunction with high-performance liquid chromatography (HPLC) and ultra high-performance liquid chromatography (UHPLC) to measure the amount of chemicals in a sample by creating charged aerosol particles which are detected using an electrometer.
OpenChrom is an open source software for the analysis and visualization of mass spectrometric and chromatographic data. [4] Its focus is to handle native data files from several mass spectrometry systems (e.g. GC/MS, LC/MS, Py-GC/MS, HPLC-MS), vendors like Agilent Technologies, Varian, Shimadzu, Thermo Fisher, PerkinElmer and others.
Whether an extended service plan is worth the extra cost depends on the item and the perceived value by the consumer. Basic service plans on desktop computers, for example, typically come close to the actual average repair cost of a system, with the retailer using the service plan as a way to keep the customer from going to a competing service center.
Test equipment is more common at this level of repair, and is used to automate many test procedures. Spare parts maintained at this level of repair are known as bench stock . Intermediate-level maintenance deployment can vary widely, and is highly dependent on desired operating conditions.
The use of extreme acidic conditions is also not recommended, as they also might hydrolyzed as well as corrode the inside walls of the metallic parts of the HPLC equipment. As a rule, in most cases RP-HPLC columns should be flushed with clean solvent after use to remove residual acids or buffers, and stored in an appropriate composition of solvent.
Agilent also provides lab management services, including enterprise asset management, laboratory business intelligence, equipment management and service, software maintenance, regulatory compliance, sample preparation, genomics and cloning, GC and HPLC columns, spectrometry and spectroscopy supplies, and consumables.

Two versions are available: one ("online") in connection with the modules of the HPLC chain is designed to control instruments and run experiments, and the other ("offline"), without a connection with the HPLC chain, is designed to analyze data. ChemStation is structured around a number of registers. Two of the more important registers are ...
Mean time to repair (MTTR) is a basic measure of the maintainability of repairable items. It represents the average time required to repair a failed component or device. [ 1 ] Expressed mathematically, it is the total corrective maintenance time for failures divided by the total number of corrective maintenance actions for failures during a ...
