HPLC has many applications in both laboratory and clinical science. It is a common technique used in pharmaceutical development, as it is a dependable way to obtain and ensure product purity. [59] While HPLC can produce extremely high quality (pure) products, it is not always the primary method used in the production of bulk drug materials. [60]
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.
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.
In this decade, affinity chromatography was invented, an ultra-violet detector was used for the first time in conjunction with LC, and, most importantly, the modern HPLC was born. Csaba Horvath led the development of modern HPLC by piecing together laboratory equipment to suit his purposes. In 1968, Picker Nuclear Company marketed the first ...
Automated systems will include components normally found on more expensive high performance liquid chromatography (HPLC) systems such as a gradient pump, sample injection ports, a UV detector and a fraction collector to collect the eluent. Typically these automated systems can separate samples from a few milligrams up to an industrial many ...
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.
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 ...
A typical multiplier for a new unit within a refinery would be in the range of 5.0. When the purchase price of all the pumps, heat exchangers, pressure vessels, and other process equipment are multiplied by 5.0, a rough estimate of the total installed cost of the plant, including equipment, materials, construction, and engineering will be achieved.
