The Aqualog is a fluorescence instrument for rapidly measuring and identifying CDOM in water. The measurement is based on fluorescence excitation-emission matrices (EEMS) corrected for all instrumental factors. These corrections require an absorbance measurement to also be performed on the water sample. Key features:• The only instrument to measure both fluorescence and absorbance spectra in a single instrument for water quali…

Scaling up is easier when using an HPLC media that provides near identical performance across all particle sizes and with increases in column diameter. The separation characteristics of each Phenomenex media offer unique selectivity for each type of application and significant production gains for maximum loadability and process economy. Achieve identical performance from analytical development to large process scale. Our Luna…

The scientists at 21st Century Biochemicals have decades of peptide synthesis and purification experience. We manufacture 100% of the peptides we sell in our laboratories in the Boston area. Unlike most other peptides companies that produce peptides off-shore or purchase peptides from 3rd parties, we control all aspects of the manufacturing process and thus you can be assured that your peptides will be of the highest quality.…

The QuickScreen One Step Benzodiazepines is a rapid, qualitative immunoassay for the detection of Benzodiazepines in urine at a cutoff concentration of 200 ng/ml. This assay is intended for use in clinical toxicology laboratories, physician's offices, and drug of abuse clinics, law enforcement agencies and on-site workplace drug testing programs. This test provides only a preliminary test result. A more specific alternate test…

The QuickScreen One Step Methadone Screening Test is a rapid, qualitative immunoassay for the detection of Methadone in urine. The cutoff concentration for this test is 300 ng/ml. This assay is intended for professional use. This test provides only a preliminary test result. A more specific alternate testing method must be used in order to obtain a confirmed analytical result. Gas chromatography/mass spectrometry (GC/MS) is th…

SPRimager®II ARRAY INSTRUMENT from GWC TEchnologies GWC’s SPRimager®II is designed for analysis of molecular interactions in an array format. The entire array is exposed to the same analyte in the 1-cm flow cell, eliminating the channel-to-channel variability inherent in multichannel systems, and allowing for simultaneous capture of data for all probes on the array.The SPRimager®II uses Surface Plasmon Resonance imaging (SPRi)…

The One Step Barbiturates Screening Test is a rapid, qualitative immunoassay for the detection of Barbiturate compounds in urine. This assay is calibrated to react with Secobarbital at a cutoff concentration of 200 ng/mL. Other Barbiturates also react (see the “Cross-Reacting Substances” section of this test instruction sheet.) This assay is intended for professional use. This test provides only a preliminary test result. A mo…
