Mobile Phase Degasser
Dissolved oxygen can cause flow rate instability and increased
baseline noise. Also, it has a quenching effect on fluorescence
detection and increases the background of UV detectors. Dis-
solved gases can out-gas in the LC system, forming bubbles in
check valves, at connections, or in detector flow cells.
In-line vacuum degassing is more effective at removing
dissolved gas from mobile phases than sonication or helium
sparging. In-line degassers work by withdrawing gas across a
gas-permeable membrane encased in a sealed chamber. Tra-
ditionally, the membrane has been made of PTFE tubing, but
the Degasys Ultimate Degasser uses tubing composed of an
amorphous fluoropolymer (AF) that is 200 to 300 times more
gas permeable than PTFE. This translates into the ability to use
shorter tubing for removing dissolved gas. This new material
also has better tubular burst strength than PTFE. To prevent
cross contamination, each channel on this Degasys unit is indi-
vidually encased within its own vacuum chamber.

To prevent system damage, do not use the Degasys system with solutions containing TFA
at concentrations greater than 5%.
Sidewinder LC Column Heater
• Easy to set up!
• Operation range: 5 °C above ambient to 85 °C, ±1 °C.
• Lightweight, compact design fits in small spaces.
• Column holder can be placed in any orientation.
This unique design completely encloses any LC analytical col-
umn up to 25 cm in length. Two lengths of heater jackets are
available: the short column holder accommodates columns up
to 10 cm in length, while the long column holder holds columns
up to 25 cm in length. The control module provides optimum
heating performance, accuracy to within 1 °C, and stability to
within 0.1 °C. The new Sidewinder controller has fast 10 Hz
sampling for improved responsiveness. The RS232 control
allows external programming.

All Sidewinder temperature control products carry the globally recognized CE mark. Each unit meets the demanding electromagnetic emission standards of the new European Union
Directives, United States standards, and Canadian standards.
Power requirements: All Sidewinder heater and heater/cooler units utilize a 24 VDC input to energize the system. This voltage is generated from a universal power supply included
with each Sidewinder unit. Also included with each Sidewinder unit is a power cable (also known as a mains cable) for use in the U.S. The power cable supplies current from a wall or
bench receptacle to the provided universal 24 VDC universal power supply.
FOR USE OUTSIDE THE U.S. If the Sidewinder unit is intended for use outside the U.S., an appropriate power cable must be purchased separately (not available from Restek).
