Gas leaks in your GC system can increase detector
noise, cause baseline instability, waste carrier gas,
and damage valuable analytical columns. Leak
checks should be a regular part of your GC mainte-
nance program. The new Leak Detective™ II elec-
tronic leak detector is the affordable solution for
detecting gas leaks. It will identify minute gas leaks
that might go undetected by liquid leak detectors.
The Leak Detective™ II electronic leak detector
incorporates microchip technology and a new design,
to give you better sensitivity and faster response time
in a more compact unit. An auto-zero feature allows
*Never use liquid leak detectors on a capillary system because liquids can be drawn into the column.
Caution: NOT designed for determining leaks of combustible gases. A combustible gas detector should be used for determining com-
bustible gas leaks in possibly hazardous conditions.

✔ Affordable thermal conductivity leak detector—every analyst should have one.
✔ Compact, ergonomic design is easy to hold and operate.
✔ Detects helium, hydrogen, and nitrogen at 1x10-4cc/sec. or at an absolute concentration as
low as 100ppm.*
you to instantly zero the leak detector with a push of
a button, and the ergonomic design brings all the
controls to your fingertips for easy use. The unit
responds in less than two seconds to trace leaks of
gases with thermal conductivities different than air.
Helium, hydrogen, and nitrogen can be detected at
1x10-4cc/sec or at an absolute concentration as low
as 100ppm.* Leaks are indicated by an audible
alarm, as well as by an LED readout. For easy, sensi-
tive, and reliable leak detection, order a new Leak
Detective ™ II electronic leak detector today.
