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.
Equipment poor-quality cost Micrometers, voltmeters, automated test equipment (but not equipment used to make the product) Indirect poor-quality costs Customer-incurred cost Loss of productivity due to product or service downtime; Travel costs and time spent to return defective product; Repair costs after warranty period
In HPLC, the capacity factor represents the molar ratio of the solute in the stationary phase to the mobile phase. The capacity factor is easily measure based on retention times of the compound and any unretained compound. The equation rewritten by Guermouche et al. [9] is presented here: 1/k¢ = [n • (KMW-1)/(f • KSW)] • CM +1/(f • KSW ...
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 ...
The set went on to sell for over $8 million at a Sotheby’s auction in early 2024, smashing records for the most expensive sneakers ever sold in history. 2. Michael Jordan’s 1998 NBA Finals ...
Every time a car experiences a mechanical failure, it gives the owner a stark choice -- to repair or not to repair. Depending on the age of the car, the cost of the car and the type of repair, the ...
Capillary electrochromatography (CEC) combines the principles used in HPLC and CE. The mobile phase is driven across the chromatographic bed using electroosmosis instead of pressure (as in HPLC). Electroosmosis is the motion of liquid induced by an applied potential across a porous material, capillary tube, membrane or any other fluid conduit.
