These systems are complementary products that can be integrated together and used along with other analytical instruments. LC is a standard technique and is utilized in a broad range of industries to detect, identify, monitor and measure the chemical, physical and biological composition of materials, and to purify a full range of compounds. MS instruments are used in drug discovery and development, including clinical trial testing, the analysis of proteins in disease processes (known as “proteomics”), food safety analysis and environmental testing. LC is often combined with MS to create LC-MS instruments that include a liquid phase sample introduction and separation system with mass spectrometric compound identification and quantification. Through its TA Division (“TA®”), the Company primarily designs, manufactures, sells and services thermal analysis, rheometry and calorimetry instruments, which are used in predicting the suitability of fine chemicals, polymers and viscous liquids for various industrial, consumer goods and healthcare products, as well as for life science research. The Company is also a developer and supplier of software-based products that interface with the Company's instruments and are typically purchased by customers as part of the instrument system.1  Description of Business and Organization Waters Corporation (“Waters®” or the “Company”), an analyticalfalsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNo definition available.No authoritative reference available.falsefalseDescription of Business and Organization12Description of Business and OrganizationUnKnownUnKnownUnKnownUnKnownfalsetrue
