2. INTRODUCTION
The VICI DBS® Mistral Gas Station includes an oil-free air compressor and delivers a continuous ow of
nitrogen with a purity of 99.5% at a rate of 25 L/min and simultaneously 35 L/min of ltered air.
The Mistral Gas Station uses pressure swing adsorption technology (PSA) to remove oxygen, carbon dioxide
and water from compressed air. The resulting pure nitrogen is ideal for laboratory applications like LC-MS and
other applications requiring inert gas.

3. SAFETY
3.1. Personal Safety Instructions
When using your Mistral Gas Station, basic safety precautions should always be followed, including
the following:
• The quantity of dust in the ambient Air can be very different from one place to another.
We recommend to replace the dust lters every 4000H. In some dusty areas, this
maintenance need to be performed more frequently.
• Clogged dust lter may damage the device or give a bad Nitrogen quality.
• The power supply main cable connector is the disconnect device in case of
emergency, it must be easily accessible at any time.
• If the Mistral Gas Station is used in a way not specied by VICI DBS, the
protection provided by the equipment could be compromised.
3.2. Instrument Safety Instructions
• The Mistral Gas Station is a nitrogen generator. Do not let it run with the outlet open to
the air in a low volume room.
• The increase of the Nitrogen (and decrease of oxygen) may cause human disease.
It is the responsibility of the user to check if the room is appropriate or if an O2
measurement is necessary.
• The Mistral Gas Station rejects oxygen as waste.
• Oxygen ratio in the air could change around the device in a low volume or not
sufcient ventilated room.
• If fuel gases are present around, their explosive or ammable limits could be
affected. It is the responsibility of the user to check if the room is appropriate or
if an O2 measurement is necessary.

5.5. Power Supply Settings
The current power supply setting of the generator is indicated on the ID Sticker at the back of the generator.
The MISTRAL GAS Station standard setting is 210-230V /50-60Hz.
If other voltages are required, this should be done when ordering. In this case a transformer will be installed
to transform internally the requested voltage to 110-115 V /50-60Hz. Below you will nd the list with possible
voltage- and frequency settings. In any case the voltage of the power supplied must stay within +/- 10% of the
nominal value.
VOLTAGE SETTING FREQUENCY FUSE F3 (5X20 OR 6.3 x 32 mm) COUNTRY
110-120 VAC 60 Hz 20 A Japan/U.S.A.
220-240 VAC 50 Hz 10 A Korea/Europe
Please see service manual for the connection of the transformer. General earth connection is done via power
supply main cable.
5.6. Transport and Storage Conditions
Temperature Minimum 4ºC (39ºF), Maximum 45ºC (113ºF)
Humidity Inferior to 90% Rh, non-condensing
Shocks and vibrations during transport Shocks <1g; Vibrations <0.2g/5Hz
Instruments position Horizontal
The above mentioned values are considered for an instrument transported in its original new packing.
The device contains castors to be moved easily. Use the breaks to make the device stable. The Mistral Gas
Station could be elevated from any points under the chassis base.
Recommendations for Transport
When the instrument is shipped back to the factory for recalibration or repair, the Mistral Gas Station should
be packed in its original packing with the inlets and outlets protected against any accidental penetration of
dust or particles of the package.

9. OPTIONAL EXTERNAL TANK
In some situation, the LC-MS devices do not need the full ow of Nitrogen. This is also the case if the LC-MS
stops. In such situation it does not make sense to have the Mistral Gas Station run continuously and throw
away the produced Nitrogen.
The Mistral Gas Station is able to handle an external tank management. The Mistral Gas Station will run until
the high set pressure (P Max Tank) is reached. Then the Mistral Gas Station will stop until the low set pressure
(P Min Tank) is reached.
9.1. Size of Tank
The size of the tank is very critical. If at the same time...
• the tank is to small
• the pressure difference = (P Max Tank)- (P Min Tank) is small
• the requested ow is high
...then the Mistral Gas Station will start and stop too often and this will damage the compressors of the device.
That’s the reason, once the Mistral Gas Station has stopped, he will not restart before 300s (5 minutes).

16
MISTRAL GAS STATION
USER MANUAL www.vicidbs.com
Version 2.00.0000
9.1.1. Tank Size Calculation
Given:
• The nitrogen consumption is 30 L/min
• The LCMS needs 7 barg (101.5 psig) pressure
...the max usable pressure of the Mistral Gas Station is 9 barg (130.5 psig). This mean that the max pressure
difference is our example is 2 barg (29 psig).
You’ll need to store at least the requested Nitrogen for the 5 minute stops of the compressors (30 NL/min x 5
min) = 150 L atm.
As we can have 2 barg (29 psig) pressure difference, the requested volume will be 150 L / 2 = 75 L
This is the minimal size tank requirements. In order to save the compressor life time, we recommend to
oversize the tank by a factor of 3.
In this example, the right size of the tank will be around 225 L
9.2. Where to Get the Tank
As the size of the tank will be large for application and in addition legislation is different from one country to
another, DBS doesn’t sell this article and let the customer purchases it locally.
Note: The tank must be compatible with pressures up to 10 bar and certied (CE marked for Europe).
Using a non-certied external tank may be dangerous and may cause human disease.
Tubing and ttings must also support the requested pressure.
9.3. Recommended Set-Up
As the size of the tank will be large for application (and legislation is different from one country to another),
VICI DBS does not sell this product allowing the customer to purchase it locally.
