High Sensitivity The SolidSpec 3700/ 3700DUV is designed for the highest sensitivity. It is the first UV-VIS-NIR spectrophotometer with three detectors: a photomultiplier tube (PMT) detector for the ultraviolet and visible region, and furthermore InGaAs and PbS detectors for the near-infrared region. The use of the InGaAs and PbS detectors makes the sensitivity in the near-infrared region extremely high. Up to now, all convent…

MicroScint™-20 cocktail was formulated to accept dilute aqueous samples at up to 20% loading (up to 25 µL in 100µL MicroScint™-20). With these sample types MicroScint™-20 cocktail mixes easily and completely upon agitation with an orbital shaker. It is the cocktail of choice for counting filters that have not been completely dried. MicroScint™-20 cocktail has an absolute, unquenched Tritium efficiency of approximately 52% when…

MicroScint™-E cocktail was developed for assays that require in-situ partitioning of the radionuclide-containing lipid phase from the aqueous phase in microplates. In this respect MicroScint™-E cocktail is suitable for extracting lipids or other non-polar compounds from the aqueous phase in such extraction assays. It enables direct counting of the samples after addition of the cocktail, because the label is preferentially take…

MicroScint™-O cocktail is suitable for counting non-polar organic samples such as hexane, heptane, ethyl acetate etc., and for dried filters. Since MicroScint™-O cocktail does not contain surfactants it is not miscible with water and is therefore unsuitable for aqueous samples. It is particularly useful for organic samples produced from enzyme inhibition assays. MicroScint™-O cocktail has an absolute, unquenched Tritium effici…

MicroScint™-PS cocktail was specifically formulated for polystyrene compatibility. It is suitable for use with virtually any type of microplate and provides long term counting stability. MicroScint™-PS has almost identical sample handling capabilities to MicroScint™-20 cocktail with respect to sample concentration and loading. MicroScint™-PS cocktail provides high counting stability with minimal change in count rate within 24…

Specifically formulated to accept up to 2.0 M ammonium formate at a 1:1 ratio with fast and easy mixing. Ultima-Flo AF will appeal particularly to those researchers using ammonium formate buffers to elute radiolabeled inositol phosphates from HPLC columns. Other samples such as 0.1 M imidazole, pH 7.5, are also easily accepted.

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.
