Amino acid analyser, L-8900

Supplier: VWR Collection
The L-8900 is a high-speed amino acid analyser with high sensitivity that is also capable of analysing physiological fluids and protein hydrolysates. It uses a reaction column filled with beads as opposed to a reaction coil. This provides a high surface area for reagent mixing resulting in a homogeneous flow which eliminates peak broadening that can occur with a coil. The ion exchange resin in the column is based on 3 µm particles that guarantee excellent resolution of the sample peaks enhancing the quality of the analysis. An internal shut off procedure acts independently of the control software to prevent column contamination.

  • High sensitivity, high speed analysis; amino acid determinations in 30 min, physiological fluid in 110 min
  • Diamond packed column without tendency to block, long column life reducing costs
  • Injection volumes from 0,1 to 100 µl, 200 place autosampler

The instrument incorporates a variable volume auto sampler, Peltier column oven and a two-channel detector with a reference wavelength for long lamp life. All necessary buffers and reagents are degassed before use and are kept under an inert gas atmosphere. Consumables, columns and the liquid waste containers can be replaced via the front door so no additional space is required at the side for maintenance. A unique post column delivery design mixes the two ninhydrin reagents just prior to the amino acid derivatisation thereby extending reagent storage by up to one year without the need for refrigeration.

Not available through VWR Int. in Denmark

Ordering information: Different types of columns are available on request. The delivery includes one 1 litre PE bottle for buffers B1-B4, B6 (empty). Hitachi AAA driver for OpenLAB CDS - factory production test for shipment to be conducted with PH analytical method.
