SKU: 186008997 Rack, Test Tube 20 port 16 x 100 mm
The Waters Test tube rack is compatible with a wide range of laboratory equipment, including the Vacuum Manifold for use with SPE Cartridges. The vacuum manifold can process up to 20 samples at once, while the extraction manifold has enhanced features designed for use with traditional silica-based SPE cartridges, as well as modifications that allow users to take full advantage of Waters Oasis Extraction Cartridges' unique performance characteristics. Because it provides a solid area to keep the sample for analysis, the 20 Test Tube Rack becomes a vital component of these processes.
Our website has a number of Waters products that you may use with the Test Tube Rack. You may look through those options, as well as other Waters equipment, on our website and shop for lab equipment to replenish your stock and add to your existing equipment portfolio. There are numerous products and column-cartridge configurations to choose from. Your column configuration should be determined by your selectivity needs, sample capacity, mobile phase, and budget constraints. If you require a configuration that is not shown on the internet or in our brochure, please contact a Waters representative for more product information and assistance.
You might also be interested in the Neutrals QC Reference Material; The Neutrals QC Reference Material is designed for use with any chromatographic systems containing a UV detector. It is intended to be used as a system benchmarking standard. The mix contains only neutral compounds. When used consistently and control charted, the QC Reference Material will provide confidence in your results, reduce troubleshooting and re-run time, and enable cross-laboratory result comparisons. This reference material is adaptable to a wide variety of separation methods. The Neutrals QC Reference Material Kit contains one ampule with 10 μL/mL acetone, 0.25 mg/ mL naphthalene, and 0.4 mg/ mL acenaphthene in 50/50 acetonitrile/water, 2 mL.
What Does Chromatography Sensitivity Mean?
Sensitivity is the measure of the signal output per unit concentration or mass of a substance in the mobile phase that reaches the detector. It is an important parameter in chromatography and is determined by various factors. In concentration-sensitive detectors, sensitivity is often expressed as the ratio of peak height to analyte concentration within the peak. In mass-flow-sensitive detectors, it is the ratio of peak height to unit mass. It is crucial for sensitivity to be solely dependent on the chemical measurement procedure and not influenced by scale considerations.
Several instrumental and chemical parameters impact the ability to detect and quantify an analyte. In an ideal scenario, high-efficiency columns produce well-resolved peaks with narrow width and good symmetry, maximizing peak height. The sensitivity and specificity of the detector also play a vital role. To achieve optimal sensitivity, it is essential to minimize interference from the separation system and reduce electronic component noise. By carefully considering these factors, chromatographers can enhance the overall performance and sensitivity of their analyses.
