The HSQ Kit™ comes with a 4.6 x 75mm column that is used in the qualification procedure.
The older version of the the HSQ Kit™ (called the PQ Kit™) comes with a 4.6 x 150mm column instead. This difference will not affect the qualification data results and the columns can be used interchangeably. The only difference for the end-user is that the HPLC runs take much less time due to the shorter column length when using the HSQ Kit™.
Hence, this a great advantage over the older model.
