TD100-xr
Enabling confident, high-throughput,
automated thermal desorption analysis
TD100-xr
™
Introducing the TD100-xr automated thermal desorber for GC and GC–MS – an unrivalled platform for the
analysis of trace-level volatile and semi-volatile organic compounds (VOCs and SVOCs) in air and materials.
Markes International has for the last 20 years been the world leader in innovation for thermal desorption. We now present the TD100-xr,
which like the other members of the ‘xr’ series incorporates new, powerful technical advances, making it perfect for a wide range of
sample types and applications.
Superior sample integrity and
traceability
■
Confidence in results through
quantitative sample re-collection of
split flows.
■
Method compliance aided by
leak-testing, water management and
addition of internal standard.
■
Enhanced traceability of samples
using barcodes and RFID TubeTAGs.
Unbeatable application versatility
Inert sample paths and extended
temperatures allow quantitative recovery
of C
2
to C
44
, including reactive and
thermally labile species... from percent to
sub-ppt concentrations.
Platform-neutral
The short, heated transfer line allows
TD100-xr to be installed on all major
makes of GC and GC–MS.
Outstanding productivity
Automated, cryogen-free, unattended
operation for up to 100 sample tubes.
Enhanced reliability
High-precision parts result in
increased robustness.
The TD100-xr gives you the following
advantages compared to every other
thermal desorber on the market:
■
Extended re-collection
■
Extended analyte range
■
Extended reliability.
Quantitative sample re-collection of all split flows
Powerful capabilities for repeat analysis and method validation
How two-stage thermal desorption works
Method-
compliant,
quantitative
analysis of
high-
concentration
stack gas is
confirmed by
re-collecting the
split sample
onto a clean
sorbent tube,
followed by
re-analysis.
All models of the TD100-xr come with the unique ability to split samples
during tube and/or trap desorption, and re-collect the split portions onto
clean sorbent tubes. With options for manual or automated
re-collection, this capability overcomes the historic ‘one-shot’ limitation
of thermal desorption, aids method development, and allows complete
analyte transfer to be validated, ensuring compliance with standard
methods.

Tube desorption and inlet split
Sample tubes
and traps can
contain multiple
sorbents, for
analysis of an
extended range
of analytes.
Sample tube heated in a
flow of carrier gas and
analytes swept onto
an electrically
cooled focusing
trap, typically
held between
ambient
and –30°C.

Extended analyte scope
From ultra-volatiles to semi-volatiles, over a wide concentration range
The uniformly inert flow path of the TD100-xr – in conjunction with tube and trap backflushing and use of optimised sorbent combinations – allows quantitative
recovery and re-collection of C

to C
44
(including reactive and thermally labile species), from percent to sub-ppt concentrations.

Landfill gas analysis
The simultaneous detection of acetaldehyde,
styrene and sulfur species (circled) in this sample of
landfill gas illustrates the ability of Markes’ TD
systems to analyse a wide compound range in one run.
A range of sub-ppt SVOCs – including
analytically challenging PAHs (circled) –
are detected in this Chinese urban air
sample, as well as typical ‘air toxic’ VOCs.

Markes’ patented DiffLok caps remain in
place on tubes throughout the entire
automated TD sequence, preserving
sample integrity while overcoming the need
to uncap and recap tubes.
Water management:
Automatic dry-purging of
water or solvent from the
tube or trap improves
chromatographic results.
Optional internal
standard/dry-purge
(ISDP) facility is ideal
for method validation.
Tube pressure-ratio
testing monitors
integrity of tube packing.
Low consumption of expensive high-purity
carrier gas minimises running costs.
GC column connection.
Re-collection of all split flows onto clean sorbent
tubes allows re-analysis and method validation.
Electronic control of split and desorb flows
(optional) increases confidence in your data and
improves repeatability.
Digital mass flow controllers give double-split
ratios of up to 125,000 : 1, accommodating
analyte concentrations up to percent levels.
True splitless operation enables analysis of
analysis of sub-ppt concentrations.
High throughput:
100 tubes for
unattended
operation over
extended periods.
Efficient electrical cooling of
the focusing trap eliminates the
need for cryogen, reducing
operational costs and ensuring
fast sample processing.
