The Holmium Oxide solution (catalog number PQA-HOX-01 or PQA-HOX-A) can be used as a stand-alone item without having to order the entire HSQ Kit. It is a component of the Kit but can be used to perform wavelength accuracy qualification on its own. You can also order it as a replacement solution if you already have the HSQ Kit.
It does not come with the Excel template included in the Kit but it is not necessary for wavelength qualification. You simply pick any or all of the 14 bands from 241 – 641 nm and compare their found values to the official values provided on the supplied certificate of analysis.
