Cap-mat 96-well 7 mm Round Plug Pre-slit Silicone/PTFE, 5/pk
Use the Cap-mat 96-well 7 mm Round Plug Pre-slit Silicone/PTFE to protect all 96 wells during short-term or long-term storage of chemicals or compounds. This single lab equipment prevents contamination and evaporation of well contents, thus ensuring that your analytes maintain their purity before or after the analysis and you get precise, dependable results every time.
The Cap-mat 96-well 7 mm Round Plug Pre-slit Silicone/PTFE is ideally suited to be used with thick and/or blunt HPLC needles that are used to transfer chemicals, solvents, and solutions between instruments.
The Pre-slit Silicone/PTFE provides adequate venting to prevent vacuum formation delivering excellent sample-draw reproducibility. It also eliminates coring from bottom draw-port needles and exhibits good resealing capabilities. It is recommended for multiple injections and has a working temperature range from -40 ˚C to 200 ˚C.
Waters recommends using the Cap-mat 96-well 7 mm Round Plug Pre-slit Silicone/PTFE in autosamplers, where it can promote proper venting, and accuracy of sample draw.

What Is Sensitivity In Chromatography?
Sensitivity is the signal output per unit concentration or unit mass of a substance in the mobile phase entering the detector, e.g., the slope of a linear calibration curve. Sensitivity is also the ratio of peak height to the analyte concentration in the peak for concentration-sensitive detectors. It is the ratio of peak height to unit mass in mass-flow-sensitive detectors. For sensitivity to be a unique performance characteristic, it must depend only on the chemical measurement process, not on scale factors.
The ability to detect (that is, qualify) or measure (that is, quantify) an analyte is dependent on many instrumental and chemical factors. In the ideal scenario, well-resolved peaks elute from high-efficiency columns (narrow peak width with good symmetry for maximum peak height). This is in addition to good detector sensitivity and specificity. To achieve maximum sensitivity, both the separation system interference and electronic component noise should also be minimized.
