This operating manual describes the use and maintenance of the INFICON 3000
Micro Gas Chromatograph (GC).
3000 Micro GC can be used to analyze alternative fuels such as natural gas,
syngas, biogas, and landfill gas. Additional applications include: refinery gases,
mine gas, furnace gas, custody transfer, well logging, environmental screening,
storage tank analysis, scrubber analyses, and monitoring volatile organic
compounds (VOC).
3000 Micro GC in combination with EZ IQ data handling and instrument control
software provides a comprehensive, easy-to-use gas analysis system.
1.1 About the Instrument
3000 Micro GC self-contained GC modules consist of an injector using
Microelectromechanical Systems (MEMS) technology, analytical and reference
columns, electronic pressure control, and a thermal conductivity detector (TCD)
also using MEMS technology.

Introduction
NOTE: When installed in a 3000 Micro GC chassis, a module is referred to as a
channel. When standalone, it is referred to as a module.
Routine replacement of parts such as septa, ferrules, or columns is not required.
This eliminates the need for frequent leak testing.
®
Samples are introduced through a 1/16 in. Swagelok
3000 Micro GC front panel. This design eliminates the need for traditional
hypodermic syringe injection through septa. The inlet pressure can be nearly
atmospheric because an internal vacuum pump connected to the column exit
eliminates column back pressure. See Table 1-1 for a summary of external

Overview
3.1 Overview of 3000 Micro GC Instrument and Accessories
3000 Micro GC is a gas analyzer with applications ranging from fixed gases
(H
, O2, N2, CO, CO2, etc.) to light hydrocarbons (methane, ethane, ethylene,
2
propane, butanes, and pentanes) and volatile organic compounds (methanol,
ethanol, benzene, etc.). 3000 Micro GC contains from 1 to 4 channels that perform
analysis in seconds. For many applications, hydrocarbons between the C
boiling range can be detected at mid-to-high ppm concentrations.
NOTE: When installed in a 3000 Micro GC chassis, a module is referred to as a
channel. When standalone, it is referred to as a module.
®
Samples can be introduced manually by a gas tight syringe, Tedlar
sample cylinder such as a summa canister. Samples can also be interfaced to
3000 Micro GC with appropriate INFICON supplied sample conditioners to
facilitate on-line analysis from bench scale or pilot plant reactors, or directly from a
process line. See Chapter 5, Accessory Installation for information on sample

3000 Micro GC utilizes a modular GC platform, which can simultaneously analyze
samples from one to four independent 3000 Micro GC channels. Each channel (or
module) is a self-contained GC that performs sample injection, separation, and
detection on a set of target components.
When installed in a 3000 Micro GC chassis, a module is referred to as a channel.
When standalone, it is referred to as a module.
Modules may be referred to as Channel A, B, C, D or 1, 2, 3, 4 from left to right.

3.3.1 Principle of 3000 Micro GC Module Operation
The major functions of the 3000 Micro GC module operation are: injection,
separation, and detection.
1 Injection: Gaseous sample is injected into 3000 Micro GC through the heated
inlet manifold. The manifold regulates the sample temperature and directs it
into the 3000 Micro GC injector flow assembly on a module. The sample is
drawn by vacuum pump through the injector sample loop and is released onto
the column.

2 Separation: As the sample gas enters the column, its component gases are
separated based on their retention or adsorption property with the column
stationary phase material. The longer the component gas is retained by the
column, the later it will elute from of the column for detection. Components may
be separated based on size, polarity, or boiling point, depending on the column.
3 Detection: After column separation, the sample gas enters the Thermal
Conductivity Detector (TCD). 3000 Micro GC employs a
Microelectromechanical systems (MEMS) TCD which operates on a
Wheatstone bridge circuit. The carrier gas enters the TCD via two pathways,
the reference path and the analytical path. The reference path contains only
carrier gas. The analytical path contains carrier gas and sample gas. The TCD
measures the difference in thermal conductivity between the carrier gas
reference and the sample gas components.
For example, the thermal conductivity of helium carrier gas at 300 K is
157 mW/m K. The thermal conductivity of methane sample gas at 300 K is
34 mW/m K.This difference is picked up by the Wheatstone bridge circuit,
generating signal response to the sample component eluted. See Figure 3-9.

3.3.2 Injector Flow Assembly
The injector flow assembly (see Figure 3-10) consists of:
MEMS injector chip—micro-machined miniature chip that injects sample into
the GC column
Injector Pilot Solenoid Valve—on/off valve that directs carrier gas to drive
diaphragm valves within the MEMS injector chip
Electronic Pressure Control (EPC) Valve—regulates the column head
pressure
Sample Manifold Plate—provides interface between the EPC valve and the
Injector Pilot Solenoid valve to the MEMS injector

3.3.3 Injectors
Depending on application requirements, 3000 Micro GC supports four different
types of injectors. These MEMS based injector “wafers” contain sample loops
etched into the wafer and micro-diaphragm valves used to direct sample and
carrier gas flow. The sample volume is controlled in EZ IQ by the Inject Time in
milliseconds (ms). The Injector Temperature can be set from 40-100
turned off.
3.3.3.1 Variable Injector (Timed)
The variable injector allows the injection volume to be changed by the user. An
inject time of 0 ms results in no injection.
Valid settings are between 10-100 ms. No significant difference in inject volume is
achieved after 100 ms.
The typical setpoint is 25 ms. Values less than 10 ms may result in repeatability
issues.
The higher the setting, the more sample is injected which results in higher
sensitivity. Actual injection volumes are on the order of a few microliters (µL) of gas.
°C or be
Variable injectors will show the matrix effect as the sample density varies with
compositional changes.
3.3.3.2 Variable Large Volume Injector (Timed)
Similar to the Variable Injector, the Large Volume Injector can be programmed to
inject a large volume. Variable Large Volume Injectors should only be used when
low sensitivity (1-10 ppm) is required. An Inject Time of 0 ms results in no injection.
Valid settings are between 10-400 ms. No significant difference in inject volume is
achieved after 400 ms.
Values less than 10 ms may result in repeatability issues.
PN 074-519-P1C
3 - 8
3.3.3.3 Fixed Injector
Fixed Injectors are unique to 3000 Micro GC. Fixed Injectors provide the best
accuracy and precision for 0.2% levels and higher.
Valid settings are between 0-50 ms. An inject time of 0 ms results in no injection.
A typical setpoint is 30 ms. No significant difference in inject volume is achieved
from inject times between 15-50 ms. Values less than 15 ms may result in
repeatability issues.
Actual injection volumes are typically 1-2 µL of gas.
Fixed volume injectors should not be used for trace levels (<200 ppm).
Fixed injectors minimize any matrix effects as sample density varies with
compositional changes.

3.3.3.4 Backflush Injector
The backflush assembly consists of:
a backflush injector
a precolumn
an analytical capillary column
The precolumn is a short section of column, whereas the analytical column is
usually longer. The precolumn and analytical column are connected in series.
The precolumn functions to prevent contaminants from entering the analytical
column. The sample first travels through the precolumn and then through the
analytical column. After components of interest enter the analytical column, the
flow is reversed through the precolumn, flushing the unwanted components to vent.
This backflushing of the precolumn prevents these contaminants from entering the
analytical column and causing deactivation or ghost peaks.
The backflush injector has two method parameters in EZ IQ software: Backflush
Time (in seconds) and Inject Time (in milliseconds). The Backflush Time
parameter on the Instrument Setup window can be changed to suit analysis
needs. Valid settings for the Backflush Time are between 0-240 s. Recommended
settings for the Backflush Time are between 6-12 s. Valid settings for the Inject
Time are between 0-250 ms.
The backflush injector can also function in a semi-fixed mode. An Inject Time of
0 ms results in a fixed volume injected and is best used for component levels from
0.1% and higher. This will result in higher precision.
The backflush injector can function in a variable volume mode. An Inject Time
greater than 10 ms will result in a higher injection volume. This used for component
levels below 0.1%.
Actual inject volumes are typically a few microliters of gas. For better sensitivity, set
a higher Inject Time, however, accuracy and precision will be negatively impacted.
Backflush times vary with column and setpoints and must be optimized for every
3000 Micro GC module.

3.3.4 Columns
Porous Layer Open Tube
(PLOT)
Wall Coated Open Tube
(WCOT)
Open (Capillary)
3000 Micro GC utilizes capillary columns for separation. Two types of capillary
columns are used: Porous Layer Open Tubular (PLOT) and Wall Coated Open
Tubular (WCOT). The capillary columns are wound into a column can, which is
installed into a module and can be heated up to 180°C. Columns are connected to
the injector on one end and the TCD on the other end using small dead-volume
fittings. Typical column flow rates range from 0.4 to 4 mL/min (cc/min) depending
on column dimensions.
PLOT columns have small particles embedded on the surface of the column. See
Figure 3-11. PLOT column separation is based on gas-solid partitioning. The most
popular PLOT columns are Molecular Sieve 5A (MolSieve), PLOT Q, PLOT U and
Alumina. PLOT columns separate according to compound polarity. Typical lengths
are 4 to 30 m with an internal diameter of 0.32 mm.
WCOT columns have a chemical stationary phase bonded to the internal surface
of the column. (See Figure 3-11.) WCOT separation based on gas-liquid
partitioning. OV-1 is a commonly used WCOT column, which separates
compounds according to boiling point. Typical lengths are 4 to 14 m, with an
internal diameter of 0.15 mm. Stationary phase thicknesses of 1.2 or 2 µm are used
for the OV-1. Other columns are also used in 3000 Micro GC, such as Stabilwax
OV-1701, etc.

Separation may be optimized by varying the column coating type and thickness,
column length and diameter, and carrier gas type. EZ IQ can further optimize
separation by adjusting column head pressure and column temperature.

3.3.5 Detector
3000 Micro GC uses a MEMS based TCD, which has a 240 nL internal cell volume.
(See Figure 3-12.) The small volume provides for excellent sensitivity. For some
components, a detection limit of 1 ppm can be achieved.
NOTE: TCD sensitivity is matrix, carrier gas, and component dependent.
The TCD uses a Wheatstone bridge design and has a sample and reference
channel. The TCD detects the difference in thermal conductivity of the gas traveling
through the reference side (pure carrier gas) versus the gas traveling through the
sample side (carrier gas plus the sample gas). When ON, the TCD filament is hot.
3000 Micro GC monitors the column pressure. If carrier gas flow is turned off, the
TCD will automatically turn off.
Figure 3-12 MEMS TCD detector
3000 Micro GC Operating Manual
3.3.6 D-Board
A Detector board, also known as a D-board, is attached to the side of each module.
The D-Board controls the module conditions and communicates module
information and setpoints to the Communications Board (C-Board, see section
3.4.2 on page 3-15). 3000 Micro GC supports two types of D-board: Enhanced and
Standard.
3.3.6.1 Enhanced D-Board
Enhanced D-Board circuitry significantly reduces solvent peak tailing, resulting in
better chromatography and improved sensitivity of peaks eluting after the solvent
peak (e.g., air). This feature is most useful for applications that involve low ppm
trace analysis in a solvent gas.
3.3.6.2 Standard D-Board
The Standard D-Board circuitry is for general purpose applications with a
mid-to-high ppm analysis requirement.

3.3.7 Module Cases
3000 Micro GC supports two types of module cases, a standard module case and
a Modbox module case.
3.3.7.1 Standard Module Case
The standard module case is used for most column types. MolSieve modules are
an exception. See Figure 3-13.
Figure 3-13 Standard module
3000 Micro GC Operating Manual
3.3.7.2 Modbox Module Case
The Modbox module allows the column to be wound in a larger diameter. The
MolSieve column benefits from this design because the column is vulnerable to
breakage when winding into a small diameter. See Figure 3-14.

3000 Micro GC Operating Manual
3.4.4 Sample Pump
One or two sample pumps are installed internally in 3000 Micro GC. There is no
flow through the sample path until the pump turns on. When the sample pump turns
on, the sample is drawn through the sample inlet tubing and the sample injectors
open for the time specified in the acquisition method. Set pump time at a minimum
of 20 seconds. If sufficient sample gas is available, increase the pump time to 60
seconds. The sample pump draws at a rate of 10 mL/min.
NOTE: For specific applications, there is a mode of operation called continuous
where the pumps can be turned off and sample gas flows continuously
through the internal tubing. Continuous operation can only be used with
variable and fixed volume injectors.
Backflush injectors cannot be used in continuous mode. In continuous
mode, the sample valve always remains on (open) and sample gas can
flush the sample inlet lines and injector.

4.1.5 Gas and Regulator Requirements
4.1.5.1 Carrier Gas and Regulator Requirements
A continuous, controlled flow of carrier gas is required.
Use high purity grade gas specifically intended for chromatographic use. All carrier
gas types should be 99.995% to 99.9995% pure.
The carrier gas tank requires a dual stage regulator capable of delivering
80 to 82 PSI of gas pressure. The regulator outlet fitting must be adapted to
Swagelok in order to connect the tubing. Use 1/8 in. fittings or 1/8 in. adapters.
Exceeding 82 PSI for the carrier gas pressure may result
in instrument damage.
To protect 3000 Micro GC and to enhance performance,
carrier gas traps must be used to purify the carrier gas
before the carrier gas is introduced into 3000 Micro GC.
A hydrocarbon/moisture trap (PN G2870A-01) is usually
sufficient.
4.1.5.2 Calibration Gas and Regulator Requirements
Obtain an ample supply of a calibration gas, specific to the analysis needs, from a
commercial vendor.
For the most accurate measurements, use a calibration gas that closely resembles
the actual sample gas composition.
PN 074-519-P1C
A regulator specific to the calibration gas cylinder should be used. The regulator
should be capable of supplying output pressure from ambient to 25 PSI. The
regulator must be clean, grease free and non-venting.
Checkout gas mixtures supplied by INFICON are not
calibration gases. Checkout gas mixtures are only used
for instrument installation and start up.

5.1.6.1 Heated Regulator
The Heated Regulator for natural gas (PN G2818A-X/G2845A-X/G2857A-X) is a
separately powered accessory that reduces the pressure of a gas sample for
introduction into 3000 Micro GC while maintaining the sample in a non-condensed
gas phase. This device is designed for use with natural gas samples introduced
through sample vessels or through sample lines connected to wellheads or transfer
points. The sample gas pressure must be 14 to 5516 kPa (2 to 800 PSI) with
thermal properties of up to 112 kJ/m
The sample enters the system through a quick disconnect fitting where it passes
through the particle filter and into a Heated Regulator. The sample pressure is
reduced to a range of 69 to 103 kPa (10 to 15 PSI) before it enters the
3000 Micro GC inlet.
A 7 micron sintered stainless steel particle filter reduces the risk of damage to
3000 Micro GC by particulate matter. The entire sample pathway, from the quick
connect fitting through the 3000 Micro GC sample transfer line, is heated to a
minimum temperature of 60°C.

Natural gas typically consists of methane and a wide distribution of other
hydrocarbons and fixed gases. The Heated Regulator is designed for the broadest
range of sample compositions that are in the gas phase at ambient temperature
and pressure.
NOTE: The Heated Regulator is not intended for use with
natural gas liquid (NGL) samples.

5.1.6.2 Heated Vaporizer
The Heated Vaporizer (PN G2819A-X/G2846A-X/G2858A-X) is used for high
pressure liquefied petroleum gas (LPG). This sample enters a pressure regulator
in the vaporizer where it expands, reducing the pressure to 52 ±17 kPa
(7.5 ±2.5 PSI). The sample is introduced into the injector through the transfer line
at a flow rate of approximately 40 mL/min. To prevent sample condensation, the
vaporizer temperature is regulated at 100 ±5°C.
This accessory is optimized for analyzing relatively clean and dry C
and C4
3
sample streams. The sample must be completely vaporous at 100°C and
52 ±17 kPa (7.5 ±2.5 PSI). Although a two micron particle filter is provided to
remove particulates that could lodge in the injector and damage the instrument,
using very dirty samples should be avoided.
NOTE: Samples with excessive water content will exhibit large water peaks.
Several analytes detectable with the Heated Vaporizer and 3000 Micro GC are
shown in Table 5-7.
