Applications

HAISIL HL “high load” columns and cartridges

are intended for applications

requiring maximum loading and selectivity.

The high surface area permits high

bonded phase loading yet the monofunctional

bonded phase and the absence of

micro-pores eliminates the problems that

plague many of the so-called “high capacity”

columns currently on the market.

The Type B silica backbone is pure,

robust, and stable under harsh conditions.

Users report satisfactory lifetime

when used for prolong periods at pH as

high as 9.
 
 

High Speed Analysis of Paraben

Food Preservatives

Parabens represent another example of

food additives that are routinely analyzed

by HPLC. Often, the food matrix being

assayed for preservative content requires

exhaustive cleanup and pre-filtration in

order to prevent clogging of columns

with nonporous or 2μm sorbents

recently suggested for this analysis. As in

the previous diet cola example, the

compounds of interest are base line

resolved under isocratic conditions. The

inexpensive HAISIL HL 5μm 20x2.1mm

cartridge column and the 50 second

analysis time contribute significantly
