Different brands of reagent cannot be used in combination.
When using a particular brand of reagent, use it with the combination (of titration reagents and dehydrating agents) recommended by the reagent manufacturer.
Otherwise, precipitates might be produced during the transition to the anhydrous state depending on the combination.
For the characteristics of a reagent and whether or not it can be used with a particular instrument, contact the manufacturer of the purchased reagent directly.
