WARNING

・The power supply voltages and power consumptions of this instrument are listed below.

The power supply voltage of the instrument is indicated on the label on the back of the

instrument. Connect the instrument only to a power supply of the voltage indicated;

otherwise, fire or electric shock could result. Check that the power supply voltage is stable and that its
current capacity is sufficient to operate all the components of the system. If not, the instrument will not
operate at its rated performance.

Installation Site Precautions

CAUTION

・The weight of this instrument is 43kg.

During installation, consider the entire weight combined with other GC components.

The lab table on which this instrument is installed should be strong enough to support the

total weight of the GC system. It should be level, stable and have depth of at least 600mm.

Otherwise, the instrument could tip over or fall off the table.

・Avoid installation sites that are exposed to corrosive gases or excessive dust.

These adverse conditions may be detrimental to maintaining the instrument performance

and may shorten its service life.

・Open the space above the 200mm, left side of the System.

There is an air intake for trap cooling on the left side of the system. When the space is little,

there is a

ossibility where you cannot show specification cooling ability.

■Precautions for Instrument Inspection, Maintenance, Adjustment and Care

WARNING

・Unplug the instrument before inspection, maintenance, or parts replacement.

Otherwise, electrical shock or short-circuit accidents could occur.

・Never remove the main cover.

This may cause injury or malfunction of the instrument. The main cover does not need to be

removed for routine maintenance, inspection and adjustment. Have your Shimadzu

representative perform any repairs requiring removal of the main cover.

・If the power cord plug gets dusty, remove the plug from

the power outlet and wipe away the dust with a dry cloth. If dust is allowed to accumulate, fire

could result.

・Replacement parts must be of the specifications given in "1.4 Component Parts" or "6.6

Maintenance Parts".

Use of any other parts may result in instrument damage and malfunction.

fter wiping off with the soft cloth where cleaning the device outside could soak the little

・

water or the neutral detergent, please wipe off the moisture with the cloth which dries.

・If any water gets onto the instrument, wipe it away immediately to prevent rust. Never use

alcohol or thinner solvents for cleaning the instrument.

They could cause discoloration.

Chapter1 OverView

1.1 Introduction

The TD-20 is used to introduce VOCs (volatile organic compounds) sampled with a sample

tube into a GCMS (gas chromatograph mass spectrometer) using the cold trap/thermal

desorption (TD) method.

With the TD method, a gas is passed through a tube (i.e., the trap tube) that is filled with

an adsorbent material so that VOCs in the gas are adsorbed by the material. The trap tube

is then heated to desorb the VOCs from the material. The trap tube is sometimes cooled in

order to increase the amount of adsorption.

In addition to the analysis of VOCs, the TD method is also used for the analysis of SVOCs

(semi-volatile organic compounds).

The TD-20 uses a thermo-module to cool the trap tube and so a refrigerant, such as liquid

nitrogen, is not required. This means that, in terms of installation conditions and running

costs, the TD-20 is superior to products that use a refrigerant.

The TD-20 can be completely controlled from the PC used to control the GCMS.。

1.5 Installation Conditions and Gas Specifications 

1.5.1 Installation Conditions

 In order to ensure proper performance, observe the following conditions.

CAUTION

In environments where VOCs are used, in addition to leakage that occurs when the cap for
the sample tube is attached or removed, VOCs are gradually adsorbed by parts making
contact with the gas, such as O-rings, and are detected* in measurement. Ensure that the
installation environment contains no potential sources of constituents that may influence
the target constituent.

*In environments where a 0.1-ppm concentration of toluene is present, approx. 5 ng o
toluene is detected in analysis.

1.5.2 Gas Specifications

In order to ensure proper performance, use gases satisfying the following specifications.

1. Carrier Gas

Gas Helium
Supply pressure 0.5 to 0.9 MPa
Purity 99.9999% min.

2. Purge Gas

Gas Dry air or helium
Supply pressure 0.3 to 0.9 MPa

Purity No dust or moisture

CAUTION

For the carrier gas, use helium gas of at least the purity specified above, including

gas discharged from the plumbing and pressure regulators, and air mixed together

due to leakage. Performance may be adversely affected if the purity is less than the

specified level.

32. Trap Tube
This Silcosteel® tube has an outer diameter

of 3.2 mm, an inner diameter of 2.0 mm, and
is filled with adsorbent. During sampling it
is cooled and during thermal desorption it is
heated rapidly. A graphite-vespel ferrule is
used at the point of connection and so there
is no air leakage. The adsorbent is Tenax
TA.

35. Sample Tray
Up to 48 sample tubes can be set in the

sample tray. Even numbers are used for the
upper levels and odd numbers are used for
the lower levels. Sample tubes must be set
in both the upper and lower levels. When a
sample tube is desorbed, the gas is purged
in the direction of the perimeter and so the
tube must be set with the end from which
the sample is injected and aspired facing the
perimeter. At the front on the right, there is
a notch only in the upper level. This position
is used to shunt the upper-level sample tube
when the lower-level sample tube is set in
the desorber unit. Do not set a sample tube
in this position.

36. Sample-Tube Heating Block
Thermal desorption is performed on a

sample tube (with its caps removed) by
bringing it into contact with the sample-tube
heating block. After thermal desorption, the
block is cooled with a fan and the tube is
returned to the sample tray.

37. Seal Block

This block performs sealing with an O-ring

in order to facilitate the passing of gas

through a sample tube (with its caps

removed). The seal block has a front side

and a rear side. The rear side (purge-gas

supply side) is not heated.
