Under some transport conditions, condensation may form inside the GC components. To
avoid injection port or detector heater unit short-circuits, allow the unit sufficient time to dry
after transport, and follow the procedure below after installation.
(1) Seal the injection port and detector without attaching a column. (Refer to the figure
below.)
(2) Remove the injection ports (INJ) and detectors (DET) from all configured analytical flow
lines to prevent the heater from turning ON.
(3) Set the column oven temperature to 300 °C and start the GC.
(4) Keep the column temperature at 300 °C for 2 hours or more.

Q Supply gases
The following gases and associated purity values are required to maintain the optimum
performance of the unit.
For detectors other than FID and TCD, refer to the instruction manual corresponding to each detector.
1.3Gas Supply Plumbing
CAUTION
1.Gas supply pressure should not exceed the maximum pressure
listed below.
Excessive pressure may break pressure control valve or other parts.
2.When sharing a gas source with other instruments, check
specifications of all instruments to be used including this unit and
supply gas so that requirements of all the instruments can be
satisfied at the same time.
1. Gas types
•Carrier gas types
(Packed FID analysis)
Both helium and nitrogen can be used. Nitrogen is more reasonable in terms of price.
(Packed TCD analysis)
Using helium or hydrogen as carrier gas helps analyzing other materials at high
sensitivity. Because hydrogen is flammable, helium is generally used for safety.
However, to analyze helium or hydrogen, use nitrogen or argon as carrier gas. Nitrogen
is convenient to analyze minor components in the air because the nitrogen peak is not
detected when it is used as carrier gas.
(Capillary analysis)
Helium is the most suitable for separation.
Although nitrogen, which is more reasonable than helium, can also be used, the optimum
separation conditions may not be reached.
•Makeup gas types
(Capillary FID)
Both helium and nitrogen can be used. Nitrogen has a slightly higher sensitivity.
(Capillary TCD)
The same gas is used as makeup gas and reference gas for capillary TCD.
Select a type of gas by the same method to select carrier gas.
2. Gas purity
Helium (carrier gas, makeup gas) : 99.995 % or higher
Nitrogen (carrier gas, makeup gas) : 99.995 % or higher
Argon (carrier gas, makeup gas) : 99.995 % or higher
Hydrogen (FID detector gas) : 99.995 % or higher
Air (FID detector gas) : Dry air (oil and other organic components eliminated)
Compressed air(must be suppressed by an oil-free
compressor and dehumidified)

Q High pressure gas cylinder precautions
WARNING
HIGH PRESSURE
Gas cylinders are under high pressure. When handling gas cylinders,
instruction and safety measures provided by the gas supplier must be
strictly observed to prevent accidents.
General precautions are provided below.
Consult state and local regulations for specific precautions.
Keep gas cylinders away from the lab, preferably outdoors, but not exposed to direct sunlight. The area must be well-ventilated. Use tubing to bring the gases to the lab.
The temperature of gas cylinders must not exceed 40 °C. Flammable items must be kept at
least 2 m from a gas cylinder.
When using high pressure gases, pay strict attention to ventilation, and perform daily leak
checks. In particular, when using flammable gases (such as hydrogen), never smoke or
allow open flame within 5 m of the equipment. Fire extinguishers must be present.
Secure gas cylinders firmly with cylinder clamps so they cannot fall over. Use oil-free pressure valves only. Never use tubing which has contacted oil. When finished with the gas,
tighten the main valve of the cylinder immediately.

Q Precautions on handling hydrogen gas
WARNING
HYDROGEN GAS PRECAUTIONS
Hydrogen can explode if it is allowed to accumulate in a poorly ventilated area.
1.Connect gas lines correctly. Hydrogen is released into the room if
the tubing is accidentally connected to the air inlet.
2.When the unit is not in use, close the main valve of the hydrogen
gas cylinder. Check for leaks at the main valve.
3.Every time the unit is used, check for leaks along the flow line from
gas cylinder to the unit interior.
4.To prevent an explosion due to a hydrogen gas leak, the room in
which the unit is used should be well ventilated. Prohibit the use of
open flame in this room.
5.Close the main valve of the hydrogen cylinder immediately after
completing the analyses. Then, turn OFF the unit and perform
normal shut-down procedures.
WARNING
HYDROGEN GAS HANDLING PRECAUTIONS
The accumulation of hydrogen gas inside the column oven can cause
an explosion.
Close all hydrogen regulator valves not in use and stop gas supply.
(When a manual regulator valve is used, turn its control to make the
pressure zero. For APC, turn off the APC for hydrogen gas.) Seal the
column connection.

1.3 Gas Supply Plumbing
CAUTION
Hydrogen gas supply precautions
Make sure that the supply pressure to the flow controller does not
exceed 500 kPa.
If the flow controller fails with a hydrogen gas supply pressure over
500 kPa, a dangerous situation exists. Lange amounts of leaking
hydrogen could cause the FID flame to expand out of the detector.
Hydrogen gas is lighter than air. If it leaks, it can accumulate near the
ceiling. Pay strict attention to ventilation so that leaking hydrogen is
vented out of the room and cannot accumulate.
WARNING
1 Installation
Hydrogen carrier gas precautions
If much hydrogen gas is released into the poorly ventilated room, it
may cause the explosion.
1.In order to prevent hydrogen gas accumulate in the room, attach
tubes to split vent, purge vent, TCD vent and ECD vent. Discharge
the gas to open air or a ventilation equipment (such as the draft
chamber).
2.Install the GC in the well ventilated area. (Ex. in the draft chamber)
3.In order to measure hydrogen gas concentration, equip a hydrogen
gas sensor in the room. Keep the hydrogen concentration low.

Use tubing with a 3 mm O.D. and 2 mm I.D. between the gas cylinder and gas chromatograph.
The use of a gas filter is highly recommended. Contaminated tubing or poor quality gases
can interfere with baseline stability.
<Option> Gas filter (P/N 221-05619-01)
This absorbs organic compounds and moisture in the supply gas, improving its
purity. The filter can be regenerated by baking in the GC oven at 250 °C with
30 mL/min carrier gas purging the filter.
Capacity: Approx. 200 mL
Absorbent: Molecular sieve 5 A

2.1Setting Analytical Flow Lines
GC-2014 does not operate normally without setting analytical flow lines. Always set
analytical flow lines before using the unit. Refer to “Chapter 3. Installing Packed Columns
and Setting Analytical Flow Lines” and “Chapter 4. Installing Capillary Columns and Setting
Analytical Flow Lines” for detailed descriptions.
Setting analytical flow lines creates the following benefits during operation.
1. Conditions of analytical parameters for
each line can be set and monitored.
For example, when the [SET] key of
the gas chromatograph is pressed,
temperatures of columns, injection
ports, and detectors as well as carrier
gas flow rate can be set and monitored
on a single screen.
2. A protective mechanism operates to
foster more stable operation conditions.
For example, when a carrier gas
cylinder becomes empty while TCD is
used, the flow controller detects an
error and automatically lowers the
column temperature and stops
conduction to the TCD filament in order
to prevent damage to the column and
TCD filament.

2.1 Setting Analytical Flow Lines
Q Analytical flow lines
An analytical flow line consists of the flow
controller, injection port, column, detector cell,
and detector amp as shown in Fig. 2.1.1.
During analysis, the flow controller feeds
carrier gas to the injection port, a sample
injected to the injection port goes through the
column to reach to the detector cell, and a
detected signal is amplified by the detector
amp to be outputted.
In order to allow the gas chromatograph to
recognize these units as an analytical flow line,
specification for the connection between them
is necessary.
For regular analysis, specify the combination
between an injection port and detector to
which a column is connected. (Refer to the
following page for setting procedures.)
Outputted Signal
Detector
amp
Detector
cell
Column
Injection
port
NOTE
Connections of the flow controller(s) and injection
port(s) and connections of detector cell(s), and
detector amplifier(s) are specified by a serviceperson
at shipment or installation. They do not need to be
specified for regular analysis.
Fig. 2.1.2 shows a representative example of
the line configuration for packed column FID
analysis using the GC-2014.
In this example, the dual INJ and dual FID are
connected with two columns and the difference
between two FID signals is outputted from the
dual FID amp. Two columns are used because
the dual INJ and dual FID are recognized as a
single unit respectively. However, this is
considered to be a single line.

Y ] [ Z ] keys.
■ Precautions for setting analytical flow lines
CAUTION
Set analytical flow lines correctly.
Incorrectly set analytical flow lines hinder the unit's normal operation
and may also damage columns or detectors at worst.
1. Specify units to be used as part of a line.
Only units specified as part of a line are temperature-regulated.
Gas is controlled only for injection ports (flow controllers) specified as part of a line.
Examples
• If an injection port that a column is connected is not specified as part of a line, carrier
gas does not flow. If the column's temperature rises in this condition, the column may be
damaged.
• To keep feeding gas to units or maintain their temperature even though they will not be
used for analysis for a while, specify the units as part of a line.
2. Remove the units not in use from a line.
Examples
• If a detector without a column stays on a line, it may damage TCD filament or cause an
error such as FID ignition error.
• If the setting for the flow controller is turned OFF without removing an injector port
without a column from a line, an error is detected and the protection mechanism works
to lower the column temperature.
• If a split/splitless injection port (SPL) without a column is not removed from a line, an
error is detected and the protection mechanism works to lower the column temperature.

-2
,”
Perform calibration in the following cases.
• When the GC and Chromatopac are connected for the first time (during installation)
• When the GC or Chromatopac is changed with other instrument.
• When a connection channel number is changed by switching a connector on the GC side
• When a two-channel board is installed on the Chromatopac and a connection channel
number is changed by switching a connector on the Chromatopac side
NOTE
Calibration is not necessary when a detector is changed (e.g. when signal to be outputted to Ch1 is
changed from TCD to FID).
The following is calibration procedures.
(1) Press the [DET] key on the GC to turn OFF the detector control.
(2) Load the BASIC calibration program.
C-R7A, C-R7Aplus: Type “LOAD “ZCALIB”” on the [Win3] key screen.

1. Do not cross the columns (L/R). It hinders correct analysis.
2. If left and right columns are extremely different (e.g. liquid quantity, flow rate), zero point may not be
achieved by turning the control on the right side of the GC unit. In this case, adjust the column flow
rate on the side that a sample is not analyzed (reference side).

4.4Capillary TCD Analysis
To perform capillary analysis using a unit with the TCD, makeup gas needs to be supplied to
the TCD joint that a column is connected to and carrier gas (called reference gas) also
needs to be supplied to the TCD joint that a column is not connected.
In order to supply makeup gas, install the detector adapter with purge (P/N 221-34012-91) to
the TCD joint. Connect the purge piping of the adapter to the dual INJ so that makeup gas is
supplied from the dual AFC through the dual INJ.
(The dual AFC is off the line and operates as an independent mass flow controller.)

Q Analytical column
・ Make sure that carrier gas is flowing through the column before increasing the column
oven temperature because the column cannot separate compounds properly when its
liquid phase is oxidized. This is especially important for polar columns. Press the
[SYSTEM] key and set a start time so that carrier gas flows for the set time prior to
temperature control of the heated zones.
・ Selection of the analysis column is very important in GC analysis. In general, select a
liquid phase whose polarity and chemical characteristics are similar to those of the
analysis target compound to obtain good peak shape. However, highly polar columns
require low temperatures and do not last long.
Therefore, when analyzing an unknown sample, begin by analyzing it on a neutral column
with a higher allowable temperature limit. Switch to a more polar column if necessary.
Q Sample injection modes(Capillary column analysis)
[Split injection]
In capillary columns, the inner diameter is small and the sample load capacity is low. Unlike
packed columns, only a small (1-2 µL) amount of sample can be injected at onetime. The
split injection mode only allows part of the injected sample to enter the column. This method
is useful for samples of high consentration or about which nothing is known.
Try to perform a split injection method first. Set the split ratio to approximately 1:50. If the
target peak is too large, increase the split ratio. If the target peak is too small or cannot be
detected, decrease the split ratio. Select a proper split ratio in this way.
If the peak is still small with a split ratio set to “1:10” or less, try the splitless injection method.
[Splitless injection]
In the splitless injection method, almost all of the sample amount injected is introduced in the
column by temporarily suspending the split flow.
This method is effective for analyzing a low concentration sample which cannot be easily
analyzed by the split injection method.
To reduce band broadening and sharpen peaks, create a temperature ramp program. The
column initial temperature is set to a temperature lower than the boiling point of the sample
solvent.
[Direct injection]
In the direct injection method, almost the entire amount of injected sample is introduced into
a wide bore column. Because the inner diameter of the wide bore column is 0.53 mm or
more, separation is not as good as that of a column with smaller inner diameter. Because
the peak shape is broad, sensitivity may not be good enough.
For the direct injection method, the WBI (Wide Bore Injection) injection port is required.
5.2Notes for Analysis
GC-2014
63
Page 76
5 Analysis
5.2 Notes for Analysis
Q Setting the heated zone temperatures
The temperature of the injection port, the column oven and the detector are set individually.
Usually, the injection port and the detector are set to a temperature 20 °C higher than the
column.
Never set the column temperature higher than the detector because the detector could
become contaminated.
When creating a temperature program, be careful not to set the final oven temperature
higher than that of the detector.
Q Column temperature program
Use a temperature program mainly to analyze samples with a wide boiling point range.
When developing analytical conditions for an unknown sample or a sample which will generate an unpredictable elution attend, use an initial program with a temperature increase rate
of approximately 10 °C/min. Based on the results, check the temperature range in which the
peaks appear, then examine the analytical conditions. This procedure facilitates time program development.
Q Injection counter
The injection port septum and the glass insert are required to be inspected and replaced
periodically. The GC-2014 probides a function which counts the number of injections. When
the number of injections exceeds the limit, you are prompted to perform maintenance. (What
is actually counted is the number of START times.)
Select the analysis counter on the [DIAG] key screen to set and reset the counter limit. Set
the limit to perform maintenance on a regular basis.
The septum/glass insert replacement cycle varies, depending on the analytical conditions
and samples. If the glass insert is easily contaminated (when analyzing non-volatile compunds for example), set a low counter limit. On the other hand, when analyzing cleaner samples, the limit can be increased.
Q Starting up the GC
Turn on the power and/or press the [SYSTEM] key to display the GC starup screen. On this
screen, specify the files used for instrument startup and instrument cleaning (column bake out).
Press [Start GC] (PF menu) to start temperature control of each heated zone accoding to the
parameters set in the file.
A start up method should be used to initialize the system once it has been turned on. Set the
start up method to “auto” to start the file as soon as the power is on; this helps with instrument recovery after a power failure.
The initial step in the startup method should be turning on the carrier gas flow. After a set
time, increase the injection port and detector temperatures. The column oven temperature
can then be set to increase. The oven temperature increases last to protect the column from
damate and the detctor from contamination. The GC-2014 is designed to control the temperatures so that the column temperature never exceeds the detector temperature, even if all
temperatures are set to increase at the same time.
A clean up method uses higher oven temperatures than those used for the analysis. After
set bake-out time, return the temperatures to their normal analytical parameter.
64
GC-2014
Page 77
Q Shutting down the GC
To shut down the system, select [Stop GC] (PF menu) on the [SYSTEM] key screen. Then,
the system stops temperature control after the period of time set as the stop time, flows the
carrier gas for the period of time set as the flow-off time, then stops.
When shutting down the GC, the temperature of each part should be decreased at first, then
the carrier gas should be stopped so that the column can be protected. It is convenient to
use the stop time and the flow-off time.
Do not turn off the power, before select [Stop GC] (PF menu).
When shutting down the GC, the heated zones are cooled, and then the carrier gas flow is
turned off. To accomplish these in the correct sequence automatically, use a stop time (this
stops temperature control at the set time) and flow off time (turns off carrier gas flow at the
set time). Do not turn off the GC without first selecting [Stop GC] (PF menu).
Q Obtaining reproducible analysis results
Follow these suggestions to obtain reproducible results:
・ Using an AOC-20i auto injector is suggested in order to inject a sample to obtain highly
reproducible results.
・ Do not increase the temperatures of unused injection ports.
・ The GC is designed to perform optimally at room temperatures of 18-28 °C. Room tem-
peratures above 28 °C will negatively inpact reproducibility.

7.3.3 Example: starting the system with carrier gas flow
In this example, carrier gas flows for a certain period of time before temperature control
begins. The length of time the carrier gas should flow depends on how long the carrier gas
flow was shut off.
• If the same column is used in the same analytical flow line as the day before:
set a START TIME of approx. 10 minutes.
• If a different column is installed on the same flow line that has been in use:
set a START TIME of approx.10 minutes.
• If the system has been out of use for a time with no column connected:
set a START TIME of 1 to several hours.

7.4.1 Screen
Select [Stop Seq] (PF menu) from the [SYSTEM] key main screen to display the stop
procedure setup screen shown in Fig. 7.4.1. “Stop Seq” is displayed only when the system is
in OFF status.
The stop procedure setup screen consists of parameters equivalent to those on the
[SYSTEM] key main screen when the GC is in system ON status, except that the current file
cannot be changed.
Parameter changes on the stop procedure setup screen are reflected on the [SYSTEM] key
main screen.

7.4.2 Parameter list
STOP TIME
Range: 0.0−6000.0 min, Default: 0.0 min
Sets the period of time after [Stop GC] (PF menu) is pressed (or after a program finishes if
the program was running) to stop temperature/detector control.
The “STOP TIME” value on the [SYSTEM] key main screen is set here.
FLOW OFF TIME
Range: 0.0−6000.0 min, Default: --- (because the gas control is set to “Cont”.)
Sets the period of time between the end of temperature/detector control and the end of gas
control.
This item cannot be set if “Flow Control” is “Cont” (that is, if carrier gas is kept flowing).
The [FLOW OFF TIME] setting on the [SYSTEM] key main screen is set here.
