074-579-P1A 13
WARNING
The MicroFID II only measures the concentration of airborne gases and
vapors that can be ionized by a flame ionization detector.
The MicroFID II automatically displays and can record the concentration
values.
The reading displayed represents the total concentration of all flame
ionizable chemicals present in the sample. The MicroFID II can display
concentration values in ppm and ppb.
WARNING
Do not expose the instrument to intense sunlight for prolonged periods.
Exposure to excessive heat may result in erroneous readings.
At low temperatures, water vapor, a by-product of the hydrogen flame, may
condense at the exhaust port. At sub-zero temperatures the water vapor
will freeze and obstruct the exhaust port. If the exhaust port becomes
obstructed, pump operation will be inhibited. Flame out may also result.

Flame Ionization Detector Operation
The MicroFID II uses a flame ionization detector for the measurement of combustible organic compounds
in air at parts-per million levels. The permanent air gases (argon, carbon dioxide, nitrogen, oxygen, water
vapor, etc.) are not ionized by the flame.
When the MicroFID II is flamed on, the internal pump draws air in through the MicroFID II inlet. This
sample air provides the oxygen necessary for combustion in the hydrogen fed flame.
Figure 1. Flame Ionization Detector
When the proper ratio of hydrogen to air is present in the combustion chamber, the flame is started
automatically with a glow plug. A thermocouple is used to monitor the status of the flame.
When the sample passes through the flame, the combustible organic compounds in the sample will be
ionized. After the compounds have been ionized by the flame, the ionized particles are subjected to a
continuous electric field between the repeller electrode at the jet (+75V) and the collector electrode.
The ions move in the electric field, generating a current, which is proportional to the concentration of the
ionized molecules in the ionization chamber. An electrometer circuit converts the current to a voltage that
is then fed to the microprocessor.
After the sample passes through the flame and has become ionized, it is vented from the detector through
a flame arrestor. The flame arrestor prevents the flame from igniting any flammable gases present in the
sampling location.

Detector Response
The MicroFID II is strictly an organic compound detector. It does not respond to inorganic compounds.
The MicroFID II’s sensitivity is highly dependent on chemical structure and bonding characteristics. The
combustion efficiency of a compound determines its sensitivity.
Simple saturated hydrocarbons (methane, ethane etc.) possess high combustion efficiencies and are
among the compounds that produce the highest MicroFID II response. Organic fuels (acetylene, refined
petroleum products), burn easily and are also extremely well detected.
The presence of substituted functional groups (amino, hydroxyl, halogens) on a simple hydrocarbon
reduces its combustion efficiency and thus MicroFID II’s sensitivity to the compounds methanol and
chloromethane, for example, are detectable with the MicroFID II but not as well as methane. A greater
number of carbon atoms can offset this loss of sensitivity due to substitution. For example, the MicroFID II
is more sensitive to n-butanol than it is to methanol.
NOTE: The FID Response Factors Technical Note is maintained on the INFICON web site:
www.inficon.com.
Support Equipment and Consumables
Compressed Gases
Cylinders of compressed gas, such as hydrogen and calibration gas, must be handled with extreme care.
When using the calibration gas bag adapter, take care not to kink or stress the tubing. For safety, the
hydrogen and calibration gas cylinders must be secured before use.
Please observe the following handling procedures:
Do not mutilate cylinders.
Do not expose the cylinders to direct sunlight.
Do not heat the cylinders. The cylinders may rupture at high temperatures.
Use only the specified regulator for the calibration gas. Confirm regulator type and material with
your specialty gas supplier.
Use only the MicroFID II Hydrogen Filling Station for the hydrogen cylinder, Part No. A1201222.
074-579-P1A 16
WARNING
Hydrogen gas is a fire and explosion hazard when exposed to heat or
flame. The lower explosive limit (LEL) is 4%. The lower explosive limit is
the minimum concentration of gas or vapor in air that will ignite in the
presence of a source of heat or sparks.
Refer to the Material Safety Data Sheet (MSDS) before handling this gas.
The MSDS will be provided by the gas supplier when the gas is ordered.
Always secure cylinders before removing the cylinder valve protection cap.
Do not drag or roll cylinders. Use a cylinder hand truck to move large cylinders.
Wear safety glasses when working with compressed gases.
Store cylinders in an upright position.
Do not store cylinders in a hazardous location.
Store cylinders away from possible sources of ignition.
Keep regulators and related equipment in the same gas service. Do not change service or adapt
equipment without consulting your gas supplier.
Refer to local shipping regulations for hydrogen supply cylinder shipping instructions.
Regulators for Compressed Gases
When connecting a regulator to a large cylinder:
Ensure the cylinder valve and regulator connection match.
Ensure the regulator construction materials are compatible with the gas, and that the cylinder
pressure gauge will withstand the cylinder pressure.
Never use the regulator as a shut-off valve. Close the cylinder valve when it is not in use.
Do not subject the regulator to an inlet pressure greater than recommended.
Do not move or detach the regulator when it is pressurized or when it is in use.
Before connection, ensure the gas cylinder valve and the regulator CGA connection are clean.
Turn the pressure control valve on the cylinder all the way out (close the cylinder). Turn the
regulator outlet to off. Open the gas cylinder valve slowly and check for leaks. Adjust the delivery
pressure and then open the regulator outlet valve.
Hydrogen Gas
The MicroFID II detector uses a hydrogen flame to ionize samples and produce Total Volatile Organic
Compound (TVOC) readings. The quality and purity of the Hydrogen gas is very important to the
accuracy of the detector.
074-579-P1A 17
You must obtain a tank of hydrogen from which you can fill the internal cylinder. When ordering hydrogen,
specify ultra-high purity hydrogen, 99.999% pure. This grade of hydrogen is also referred to as Grade 5 or
Ultra zero grade. The hydrogen must have less than 0.1 ppm hydrocarbon contamination.
You can obtain the hydrogen in various size cylinders and pressures. Specify a tank with no more than
2400 psig (16547 kPa).
The hydrogen cylinder must also have CGA 350, male outlet.
The MicroFID II Hydrogen Filling Station Part No.A1201222 is required to fill the MicroFID II hydrogen fuel
cylinder. You cannot fill the MicroFID II hydrogen cylinder without the MicroFID II hydrogen filling station.
Calibration Gas
Adequate ventilation must be provided when the MicroFID II is being calibrated.
If compound threshold limit values (TLV) are exceeded, you should use a gas bag for sampling and
calibration.
To determine the TLV of the compounds contained in the calibration gas, refer to the Material Safety Data
Sheet (MSDS) supplied with your calibration gas cylinder.
Oxygen Concentration Limits
A minimum of 17% oxygen is required to start the hydrogen flame. The oxygen is supplied from the
sample as it is drawn in by the pump. A minimum of 10% oxygen is required to maintain the hydrogen
flame. An oxygen deficiency will reduce the height of the flame or cause the flame to be extinguished and
may affect the displayed reading.
If the MicroFID II is used in a highly contaminated area where it is possible that the oxygen content is
below 10%, watch for indications of reduced flame height such as lowered detection limits or a flame out
fault.
Flammable Gases
High concentrations of flammable gases (gases within their flammable range) can act as an additional
fuel source. When this happens, the flame height may increase beyond the confines of the combustion
chamber. The hydrogen supply will then be cut off and the flame will go out.
Flame out may also occur when the concentration of sample gas is so great that it causes an oxygen
deficiency. This may occur when sampling enclosed or confined spaces where vapors and gases cannot
escape. Watch for indications of increased flame height such as erratic readings or sudden high
concentrations followed by a flame out fault.
074-579-P1A 18
WARNING
The MicroFID II is not classified for use in hazardous locations with nonintrinsically safe rated computers.
ACCESSORIES
Computer
The MicroFID II will send information stored in its logged memory or will continuously stream data to a
computer or PDA via Bluetooth wireless communication. This feature may be used if you need to prepare
reports based on the MicroFID II recorded data.
Information prepared on a PC such as “routing or tag information” may be uploaded to the MicroFID II via
Bluetooth as well.
Gas Sampling Bag
A gas sampling bag can be used for calibration of the MicroFID II. If you are unsure of the quality of
ambient air you should use an additional gas bag filled with zero air. Connect the sample bag to the inlet
fitting with the gas bag adapter. See Calibration section for more information.
One sampling bag is included in the MicroFID II calibration kit Part No. MX396011. Additional gas bags
are also available (Part No. MX396017).
Charcoal Filters
A charcoal filter (Part No.MX396022, package of 10) may be connected to the MicroFID II during
calibration and sampling to provide clean air to the MicroFID II. The filter will remove hydrocarbon
contamination from room air to provide zero grade air to the MicroFID II.
NOTE: The charcoal filter does not filter methane or ethane. If these compounds are present, you should
use a gas bag with a supply of commercial zero air for calibration purposes.

To connect a charcoal filter:
1. Load the Teflon ferrules into the nut. The nut and ferrules are supplied with the filter. See
Figure 3.
2. Connect the nut to the MicroFID II inlet. Do not tighten the nut.
CAUTION: Over-tightening the Teflon ferrules will result in damage to the ferrules.
3. Remove the charcoal filter from its plastic bag and insert it into the nut. Finger-tighten the nut
onto the inlet. If the filter is not secure, ensure you have inserted the tube stub far enough into
nut. Do not over-tighten the fitting.
Figure 3 Connecting the Charcoal Filter
The charcoal filter will remove hydrocarbon contaminants for up to 4000 ppm hours. This means that the
filter will be good for 1 hour removing 4000 ppm of hydrocarbon contaminants or will last for 4 hours
removing 1000 ppm. The exact time will be determined by the operating environment. You will notice an
increased hydrocarbon background when the filter requires replacement.
To replace the charcoal filter:
1. Loosen the nut on the MicroFID II inlet.
2. Remove the used filter.
3. Insert the new charcoal filter into the nut and finger-tighten the nut onto the inlet. Do not over-
tighten the fitting.
4. When the charcoal filter is not in use, place it in its plastic bag and store it in a clean, dry place.

Using the MicroFID II Battery Charger
READ THESE INSTRUCTIONS BEFORE USING THE CHARGER
The MicroFID II battery charger is only designed for indoor use
and should not come into contact with water or dust. In order to
avoid overheating, the charger should not be covered when it is
in use.
The charger is turned on by connecting it to the mains socket.
Disconnecting it from the mains socket turns the charger off. If
the charger is equipped with a mains cord, verify that the cord
has not been damaged. If the cord is damaged, the charger
must not be used.
The charger contains dangerous voltages and the cover should not be removed.
CHARGER FUNCTIONALITY
This charger is a fast charger for NiMH batteries. The charger will automatically charge the battery at a
fast rate, and then charge to a slow rate near the end of the cycle. This prevents over-charging.
CAUTION: Do not charge batteries at too high or too low temperatures. Charge only in areas between
38-110°F (3-43°C).

HOW TO USE THE CHARGER
The Charger is started by connecting the battery pack to the charger. Once connected, the indicator LED
will start Orange, for the Initialization and Analysis Phase, before switching to Red for the Fast Charge
Phase. When the batteries are fully charged, the charger will go into a top-off charge mode before it goes
over to trickle charge mode. During top-off charge, the LED will be Green with short intermittent Orange
light. When the top-off charge is completed, the charger will go into trickle charge mode and the LED will
be Green. The charge current is now reduced to a safe level, which allows the charger to stay connected
to the NiMH batteries without damaging the battery. If the battery voltage is far below normal, the charger
will cut off the fast charge current and go to trickle charge mode. The LED will then indicate ‘error’ by
flickering Green and Red light. If the mains is turned off, the charger will reset and start a new charge
cycle if the mains is turned on again. If new batteries are to be connected, the charger must idle for
approximately 15 seconds to make sure all parameters in the microprocessor have been reset. The LED
changing to Orange light shows this and a new charge cycle can begin.
.
CHARGE CYCLE AND LED INDICATIONS
With mains connected, the LED will be orange the first 5-7 seconds, and will be orange when the
initialization and analysis starts. If a battery is connected, the actual charging will start a few seconds later
when the LED changes to red.
CAUTION: Use only Battery Charger P/N 1201221 to charge the MicroFID II.

To Charge the Battery
1. To charge the MicroFID II battery, unscrew the cover for the charging connector cap.
2. Connect the charge adapter to the MicroFID II charging connector.
3. When the battery charge indicates there is a full charge to the battery, disconnect the charge
adapter from the MicroFID II charging connector
4. Install the charging connector cap to the charging connector.
074-579-P1A 24
NOTE: The MicroFID II will not operate without the charging connector cap in place.
NOTE: The MicroFID II will not operate with the AC Adapter plugged into the MicroFID II.
Repeat Charging with an AC Charger
If the AC charger has been plugged into an electrical outlet and has been used to charge a FID, and
another charging operation is to be performed, please remove the charger from the unit and wait until the
status LED on the charger changes from either green or red to orange before plugging it into the second
unit.
NOTE: The status change will take up to 15 seconds and the orange LED indicates that the unit
is ready to start a new charge cycle.
CAUTION: If the AC charger is not properly reset according to the above instructions, it is
possible that the AC charger will remain in trickle charge mode and the FID battery will not
receive a full charge. This will limit the FID’s operating time and may cause problems in lighting
the FID flame due to low voltage.
Filling the Hydrogen Fuel Cylinder
The MicroFID II hydrogen fuel cylinder is a metal hydride design that requires relatively low hydrogen
pressure to fill it.
Figure 7. MicroFID II Hydrogen Cylinder
074-579-P1A 25
WARNING
Hydrogen storage on the metal oxide is an Exothermic Reaction. The
cylinder may become hot during the initial fill. Care must be taken to avoid
injury.
WARNING
DO NOT attempt to fill the hydrogen cylinder without a refill adapter..
The hydrogen fuel cylinder (see Figure 7), when full, will provide the MicroFID II with up to 70 hours of
continuous operation in a single fill. To fill the hydrogen fuel cylinder, the MicroFID II hydrogen filling
station Part No. A1201222 is required (see Figure 8). The hydrogen fill station is outfitted with a CGA 350
adaptor for use with a high pressure hydrogen cylinder that contains at least 99.999% pure grade
hydrogen (also known as ultra high purity hydrogen).
CAUTION: H2S, SO2, Cl2, and CO are contaminating substances for the cylinder alloy. Do not expose the
cylinder interior to these substances.
CAUTION: Lower grades of hydrogen will damage the fuel cell with impurities and decrease the overall
longevity of the fuel cell. Ensure the hydrogen is ultra high purity.
CAUTION: Do not modify or alter the hydrogen cylinder or fittings.
The Hydrogen Filling Station (Part No.A1201222) consists of an adapter fitting with a left-handed thread
for cylinder attachment, an output valve and a hydrogen fuel cylinder quick connect. The Hydrogen Filling
Station delivers a fixed 260 psi to the hydrogen fuel cylinder. The output valve is positioned to deliver gas
from the cylinder to the hydrogen fuel cylinder. Additionally, in the final stages of filling the hydrogen fuel
cylinder, the output valve is used to release gas held in the quick connect after filling.
The MicroFID II Hydrogen Fuel Cylinder is composed of metal hydride material. The process of filling this
cylinder involves the low pressure adsorption of hydrogen on the metal hydride surface, rather than the
high pressure filling process for conventional hydrogen cylinders. Table 2 illustrates the charge time
versus fill time for the MicroFID II hydrogen cylinder.
A 5 minute charge provides 10 hours of usage. Other charge times versus usage are as follows:
5 minutes 10 hours of use
10 minutes 30 hours of use
30 minutes 50 hours of use
60 minutes 65 hours of use
The hydrogen fuel cylinder is over 85% full after one hour. Thereafter, the cylinder charges more slowly
up to the full 70+ hours.

WARNING
Use only the MicroFID II Hydrogen Fill Station p/n A1201222 to fill the
hydrogen cylinder. Use of any other filling device will void the warranty.
WARNING
The regulator pressure is set at the factory Do not adjust the regulator on the
hydrogen filling station. Adjustment of the hydrogen filling station regulator
will void the warranty.
WARNING
Do not exceed 260 psi when filling the MicroFID II Hydrogen Cylinder. The
fuel cells in the hydrogen cylinder will be damaged and will void the
warranty.
