This TMB X-tra with red indicator combines all the important qualities of TMB X-tra eliminating possible mistakes during pipetting.Further the red colour may be useful in automatic analyzers giving the warning “Reagent low” when it is time for filling up the substrate. The red indicator disappears after addition of the stopping solution and will neither affect the sensitivity nor the stability of the substrate.

In 2008 Gentronix launches a new S9 protocol to extend the application of the GreenScreen HC assay to include the detection of genotoxic metabolites. Many pharmaceuticals only present a genotoxicity hazard after metabolism and such chemicals are called pro-mutagens or pro-genotoxins. Generally, although not exclusively, the liver is considered responsible for the “metabolic activation” (MA) of promutagens. However, none of t…

Waters offers PoraPak™ Rxn, a family of polymer-based chromatography products for superior cleanup of synthetic reactions. PoraPak Rxn products are available in two chemistries: PoraPak Rxn CX, a strong cation-exchange sorbent and PoraPak Rxn RP, a reversed-phase sorbent.PoraPak Rxn sorbents are based on copolymers that exhibit the following properties:Hard material that does not develop increasing back pressure with flowLitt…
SDB-XC is a poly(styrenedivinylbenzene) copolymer used as a reversed phase sorbent for solid phase extraction. SDB-XC is not bonded to silica but is a 100% copolymeric particle that is spherical, porous and cross-linked. It does not exhibit the secondary cationic (silanol) interactions and pH limitations common to bonded silica sorbents, so it offers more predictable and reproducible reversed phase interaction.
Cation-SR is a poly(styrenedivinylbenzene) copolymer that has been modified with sulfonic acid. Note that Cation-SR is not bonded to silica but is a 100% copolymeric particle that is spherical, porous and cross-linked. The functional group imparts selectivity for cationic analytes, such as primary, secondary and tertiary amines.
3M Bioanalytical Anion-SR is a poly(styrenedivinylbenzene) copolymer that has been modified with quaternary ammonium groups. Note that the 3M Anion-SR is not bonded to silica but is a 100% copolymeric particle that is spherical, porous and cross-linked. The functional group imparts unique selectivity for anionic analytes, such as Endothall, Dalpon and haloacetic acids.
The Oil & Grease Disk was specifically designed for EPA Method 1664 (N-Hexane Extractable Materials (HEM) and Silica Gel Treated N-Hexane Extractable Material (SGT-HEM) by Extraction and Gravimetry). EPA Method 1664 Revision A was approved for use in the United States and published in the Federal Register on May 14, 1999. The Oil & Grease Disk incorporates C18 sorbent particles within a hydrophobic matrix. For EPA Method 166…
Empore™ Chelating Disks provide a way to selectively remove multivalent metal cations from solutions. This selectivity can be used to concentrate metals from a sample for analysis or to isolate and remove metal interferences from a complex organic or inorganic sample matrix. In the latter case, the purified filtrate is ready for use. The chelating disk has an affinity for multivalent (primarily 2+ and 3+) transition element…
Empore Carbon Disks are designed for the extraction of volatile, highly polar, and water soluble compounds from aqueous solutions. The Empore Carbon Disk provides all the advantages of activated carbon in a compact and thin Empore Disk.
Commonly used for the solid phase extraction of analytes from complex sample matrices. A variety of functional groups, such as octadecyl (C18) and octyl (C8) can be bonded to the silica surface to provide non polar interactions. Each of these sorbents exhibits unique properties of retention and selectivity for a particular analyte. The choice of which sorbent is best for a particular method will be influenced by the percent…
