Waste Overflow Indicator
for LC Systems
• Avoid messy pooling around mobile phase waste containers.
• Audible alarm instantly alerts user, preventing overflow.
• Compact, battery-operated unit.
• Available for 4-liter and GL-45 solvent bottles.
The Restek® waste overflow indicator will help keep your mobile
phase waste where it belongs—in the waste container! Com-
pact, battery-operated unit fits securely on solvent bottles and
accommodates two waste streams. An audible alarm is given
as the solvent waste container approaches capacity, giving you
time to empty or change the container. Another innovative
design from Restek!

tech tip
Mobile Phase Additives with LC-MS
Mobile phase additives such as triethylamine, trifluoroacetic acid,
and ion-pairing reagents can compete with sample ions, decreasing
sensitivity and, in some cases, reducing sample ion intake into the
MS. To obtain symmetric peaks and/or sufficient retention, use base
deactivated silica, like Pinnacle® DB or high purity silicas like Ultra or
Raptor™, that minimize the need for additives.
