The ACQUITY UPLC / UV Qualification Standards Kit is a mixture of organic chemicals that are present at levels <0.4% in a matrix of 10/90 acetonitrile/water packaged in 10 ml flame sealed amber ampoules.
The standards included in the ACQUITY UPLC / UV Qualification Standards Kit are appropriate for verification of system reproducibility, flow rate, and gradient performance. In addition to this, they can be used to determine detector linearity, detector accuracy, injector accuracy, and injector carryover.
There are numerous advantages of using the ACQUITY UPLC / UV Qualification Standards Kit. They save time because no preparation is required. They are also inexpensive compared to other calibration standards. As with all Waters products, the ACQUITY UPLC / UV Qualification Standards Kit includes a certificate of analysis
for traceability. In addition to this, the standards have been shown to have excellent stability. Waters offers standards that are pure, reproducible, precisely formulated, and traceable. These standards are crucial lab equipment as they offer solutions to help improve productivity while ensuring the accuracy and reliability of your data.

What Is Retention Factor [k] In Chromatography?
The Retention Factor is the measure of the time the sample component resides in the stationary phase relative to the time it resides in the mobile phase. Essentially, it shows how much longer a sample component is retarded by the stationary phase compared to when it would take to travel through the column with the velocity of the mobile phase. Mathematically, it is the ratio of the adjusted retention time [volume] and the hold-up time [volume]: k = tR'/tM. Retention factors are especially useful in comparing the results of one chromatogram to the results of another. If the conditions in which the chromatograms are run are unchanged, that is they both use the same mobile and stationary phases, the retention factor for a given material should remain constant.
