Fixed analyzer monitors
methane and more
The Landtec Biogas 3000 fixed gas
analyzer (photo) provides continuous
monitoring of gas-producing applications
such as anaerobic digestion,
biogas and landfill operations. It can
use up to four sample ports to monitor
methane, carbon dioxide and oxygen,
with optional monitoring of hydrogen
sulfide, hydrogen and carbon monoxide
levels. The device is easy to install,
calibrate and maintain, says the
company. Recently added capabilities
include a built-in liquid level monitoring
feature equipped with a dedicated
alarm and moisture-removal drain,
and an automatic drain option that
empties the catchpot without manual
intervention, offering flexibility for onsite
maintenance. - QED Environmental

Improved flow modulator
supports broader GC use
Insight (photo) is a flow modulator
for routine, comprehensive, twodimensional
gas chromatography
(GCxGC). Thanks to simplified technology
that avoids the use of liquid
nitrogen, this device helps to reduce
the cost and ownership of GCxGC
systems, whose complexity often
presents a major barrier to use for
some laboratories, says the company.
Insight uses precise control
of gas flows to simply fill and flush a
sample loop to fractionate the firstcolumn
effluent and deliver it to the
second column. The simplified design
is said to fit easily inside standard
GC ovens, and uses reverse fill/
flush dynamics to provide improved
peak shape and increased peak capacity
for GCxGC compared to firstgeneration
flow modulators. Insight
provides separation of volatiles from
C1 to C40 and above without using
liquid nitrogen, and eliminates modulation
breakthrough for improved
characterization of both high-loading
and trace components. - SepSolve
