The carefully matched optical paths of the spectrophotometer also minimize noise and drift. Overall system noise is =s±5 χ 10 4 absorbance unit from 210 to 780 nm; drift is lower than 10 2 absorbance unit/hour—performance specifications which ensure that you will see more with Variscan than with any other LC detector. LC is no longer detector-limited. Now it is possible to detect and analyze a much broader range of compounds. Pardon our French, but you really can see one hell of a lot more with Variscan.
