HPLC Buffers

Fluka is expanding its HPLC auxiliaries and reagents portfolio steadily. Currently we offer more than 30 application tested reagents. For most of the products the following quality controll tests are performed:

RP gradient: to test correspondance with standard
Solubility: to test whether the solution is clear
Residue: to test whether there is no residue in the filter (millipore^® 0.45 mm membrane filter)
UV Absorption: to test correspondance of the maximum UV absorption at a HPLC relevant wavelength with standard
pH: to test whether the pH of the aqueous solution corresponds
Cyclic Voltammogram: to test whether it corresponds

The table below lists the recently launched HPLC grade products:
