HPLC is distinguished from traditional ("low pressure") liquid chromatography because operational pressures are significantly higher (around 50–1400 bar), while ordinary liquid chromatography typically relies on the force of gravity to pass the mobile phase through the packed column. Due to the small sample amount separated in analytical HPLC ...
Waters Corporation is an American publicly traded analytical laboratory instrument and software company headquartered in Milford, Massachusetts. The company employs more than 7,800 [ 2 ] people, with manufacturing facilities located in Milford, Taunton, Massachusetts ; Wexford , Ireland and Wilmslow , [ 3 ] Cheshire .
Chromatography columns of different types are used in both gas and liquid chromatography: Liquid chromatography: Traditional chromatography columns were made of glass. Modern columns are mostly made of borosilicate glass, acrylic glass or stainless steel. To prevent the stationary phase from leaking out of the column interior a polymer ...
Liquid chromatography (LC) is a separation technique in which the mobile phase is a liquid. It can be carried out either in a column or a plane. Present day liquid chromatography that generally utilizes very small packing particles and a relatively high pressure is referred to as high-performance liquid chromatography.
[35] [36] An example of a chromatographic technique that can aid in signal in ESI involves using 2-D liquid chromatography, or running the sample through two separate chromatography columns, giving better separation of the analyte from the matrix.

Wyatt Technology has been named one of the “Best Places to Work in Industry” by The Scientist magazine from 2008-2013. [17] Wyatt Technology's Optilab rEX differential refractometer was awarded the 2004 Pittcon Editor's Silver award, [18] and was also named, by R&D Magazine, one of the top 100 innovative new products of the year.

A chromatography detector is a device that detects and quantifies separated compounds as they elute from the chromatographic column.These detectors are integral to various chromatographic techniques, such as gas chromatography, [1] liquid chromatography, and high-performance liquid chromatography, [2] and supercritical fluid chromatography [3] among others.
