Thermal Desorption Systems:
Installation Checklist (i) - UNITY 2
If other TD components are to be installed on this system – please refer to the relevant checklist
documents prior to commencing UNITY installation
Purpose of Procedure
This procedure insures that instruments and systems are installed and functioning as designed.
Correct installation is the first step in ensuring that instruments and systems operate reliably over
their lifetime. This checklist is designed to help our service representatives provide you with
consistent, quality service.
Customer Responsibilities
Make sure your site meets the basic requirements, including: the necessary space, electric
outlets, gases, tubing, operating supplies, consumables and other usage dependent items
required for the successful installation.
Refer to the Agilent Technologies Document “Markes Series 2 Thermal Desorption Systems Site
Preparation” for further information.
If Agilent is delivering installation and familiarization services, users of the instrument should be
present throughout these services; otherwise they will miss important operational, maintenance
and safety information.
This checklist outlines the tasks associated with installing the Agilent Thermal Desorption
equipment.
Important Information
The installation service does not include:

Network setup with other computers or to the building network

Customization of the system

Method development and testing

Analysis of customer standards or samples
If you need assistance beyond this installation service, please contact your local Agilent
Technologies office. Assistance with this checklist and user specific services and applications is
available and will be contracted separately.
Site and shipment inspection
 Discuss the installation procedure with customer.
 Customer’s site meets minimum specifications, especially for line voltage, electrical outlets,
gas purity and -50°C dewpoint of dry air/nitrogen.
 Customer’s GC / GCMS and data system is installed and operating correctly

Installation
Installation should be completed by referring to the detailed Installation Instructions found on the
Technical Documentation CD supplied with the instrumentation. E.g.

UNITY 2 installation manual

Air Server Installation manual

Electronic Carrier Control (ECC) manual

UNITY 2 MFC installation manual
Take care to observe all warnings and notes given in these installation manuals.
The following checklist should be worked through sequentially.
Air Server module – if applicable
 Fit AS3 / AS8 module to the side of UNITY
 Connect wiring
Mass Flow Controller (MFC) modules – if applicable.
Determine the number and location of MFCs to be installed (use the table below as a guide)
CARE: Ensure power to UNITY remains switched off during MFC installation

 Replace copper tube vents with PEEK tubing connections between MFC and UNITY
 Make cable connections
Install transfer line, trap and split tube.
 Install heated transfer line fittings and connections
 Install fused silica insert, ensuring insertion depth at UNITY end is 20 mm from the back of
the 1/16” stainless steel nut
 Install split tube
 Before installing the cold trap, check the alignment between the heated valve and the cold
trap assembly using the metal cold trap. Remove the metal cold trap and install the cold
trap. (CARE: Ensure power to UNITY remains switched off during trap installation).
Plumb gases and connect cables
 Connect the carrier gas and purge gas to the back of the U-GAS01
 Refer to the UNITY 2 ECC Installation Manual and make the carrier gas connections from
U-GAS01 to the GC according to the GC model being used.
 Ensure that the Inlet Settings on the GC are set up correctly (refer to the ECC Installation
Manual).

□
Change inlet to splitless mode
Set purge time to 999.99 on the GC keypad
Turn Gas Saver OFF
 Make the purge gas connections from U-GAS01 to UNITY 2
 Connect the power cable
 Connect the UNITY 2 to the GC using cable MKI-UTD-5098
 Connect UNITY 2 to the PC using cable MKI-Z-0189
 Switch on carrier gas supply. It is recommended that carrier gas is supplied to U-GAS01 at
~ 10psi higher than that required by the system. System carrier gas pressure should be
between 0 and 60psi and is determined by the GC column
 Switch on the dry purge gas supply. It is recommended that purge gas is supplied to UGAS01 at ~ 10psi higher than that required by the system. Recommended line pressure
for the system is 50 psi ±5psi.
 Once carrier gas is supplied check all connections, including around transfer line and trap,
for leaks with an electronic Helium leak detector.
Install software and check communications
 Insert the software CD (part number) into the appropriate compartment of the controlling
PC and follow the instructions on screen
 Switch on UNITY 2 and establish communication.

 If required go to “Options” and set up “Communications Port” and “GC Interface logic” on
the “Ports” tab
 If MFCs are fitted

Set up MFC position, flow range and designation in “Options” “Flow Control” tab and
Gas type on “Gas” tab

Calibrate MFC using information supplied on yellow label attached to MFC (retain
label for future use)
Condition cold trap
Refer to the Trap Certificate supplied with the cold trap for typical trap conditioning temperatures.
Note that if you are installing a trap other than the standard U-T11GPC-2S trap supplied with
UNITY, then additional – extensive – conditioning processes may be required over and above
these instructions.
 Under the “Miscellaneous” tab of “Options”, select “Use Controlling Method Parameters”
under “Trap Heat Method”
 Ensure the “Trap Settings” of the controlling method has a pre-trap purge time of at least
1.0 min
 Ensure the “Trap High Temperature” is compatible with the temperatures given in the Trap
Certificate.
 Select “Set Gas Flow” function answer “Yes” to the question “Set Gas Flows with Split On?”
 Set both trap flow and split flow to 50ml/min
 Click “Heat Trap” icon and answer “Yes” to “Heat Trap with the Controlling Method
Parameters”
System Checkout
 With “Split On in Standby” selected, ensure air/water background of MS is within
operational limits
 Create a new method using parameters set out in documentation supplied with check
standard QQR-0190
 Set up appropriate gas flows
 Set suitable GC(MS) parameters for the analysis of benzene, toluene, xylene, camphene
and di-octyl phthalate
 Run the UNITY check standard
 Assess the results
 Before leaving customer site go to Help – System Info and print a copy of the calibration
settings
