Lithium Diluent Li220

Description

Product Description: Lithium Diluent Li220

The Pickering Labs Lithium Diluent Li220 is formulated to a pH of 2.36. This Lithium Diluent Li220 is used for diluting samples and standards for analysis with Lithium columns and buffers on your post column derivatizer. This bottle comes in a case of (4) 250 ml bottles. The Pickering Labs Lithium Diluent Li220 contains: (4) 250 mL Bottles of Pickering Labs Lithium Diluent at a pH of 2.36. Our part number is KDT-DIL-Li220-N.  This is used in Pickering Laboratories PCX post column derivatizer systems operating with a Liquid Chromatography HPLC system.

Chromatographic Grade'” Samples and Standards Diluents for Amino Acid Analysis:

Use of these diluents is essential to ensuring reproducibility from injection to injection. They establish a uniform pH and ion concentration at the outset, regardless of the source and pre-treatment of the sample. The sample is maintained buffered and at optimum pH for sample storage and analysis.

Use Li220 for prepared physiological samples and to dilute amino acid calibration standards for use with Lithium columns and buffers.

Use Na220L for hydrolysate samples and to dilute amino acid calibration standards for use with Sodium columns and buffers.

The derivatization of primary amines with o-Phthalaldehyde and a mercaptan requires basic conditions. To ensure the optimum pH of the reaction it is important to use the correct diluent. Three application specific diluents are available: CB910 for Carbamate and GA104 Glyphosate analyses respectively, and OD104 for analysis of amino acids and other amines. These borate buffers are produced from starting materials which are free of heavy metals and amines. As with most other products of Pickering Laboratories, the quality of the OPA Diluents is verified by actual post-column HPLC analysis.

KayDee Tek also carries these other reagents for post column method.
