Gax Mixer Manager Software Part 1

Now it is time to review the last part of this video tutorial regarding the Gas Blender 100 series.

After the driver and software installation, double click on the gas mixer manager icon on your desktop.

First click on the scan device button on the drop down menu and you will see a list of MCI gas mixing devices connected to your personal computer. Select gas blender 100. To connect click on the button labeled connect device. Now we are connected to the gas blender.

Let's now take a look at the main features of the gas mixer manager softare:

Here you can see the gas blender's temperature.

Here you can see the total mass flow rate of the gas mixture. The mass flow rate is now set to 0 since we are not mixing gases. The mass flow rate value may be changed here;
for instance let's set it to 200 sccm. Through this panel we can set the parameters of each channel of the gas blender 100. Each line corresponds to a specific channel of the gas blender.

Here is displayed the gas which the channel was calibrated for.

Here we have the concentration rate that each gas gives to the mixture's creation.

Here is displayed the mass flow rate expressed in sccm units that will be provided from each channel. This value's calculation is based on the set percentage for the channel and on the gas mixture's total mass flow.

Here is displayed the real time provided mass flow rate for each channel. For example let's go to set our gas mixture features. Set the channel 2 from 30% to 25% and set the channel 3 from 20% to 10%. Then we can set the desired total mass flow flow rate for the gas mixture - for instance 200 sccm.

To start the gas mixture supply, click here on the button labeled "start gas mix". This graph displays the supplied mass flow rate for each channel over time. The mass flow rate value is displayed in these indicators: this one is for channel one, channel two , channel three. There is also an indicator the gas mixture's total mass flow rate.

The total mass flow rate can change during the mixing. Let's set it to 300 sccm for instance. As you can see the change is a real time change. This is one of the most important features of the gas blender 100 series because the response time to a change of set point value occurs within 50ms which happens to the fastest response time for this kind of gas mixing instrument on the market.

The total mass flow rate can also be changed by regulating this button. Even in this case we can witness the extremely rapid response time of the gas blender on the mixture's set parameters.

In addition to the changes on the total mass flow rate during the mixing we are also able to change the concentration for each channel. for example we can change the concentration value for channel 2, decreasing it from 25% to 20%, and then the concentration value for channel 3, increasing it from 10% to 35%. Again changes are immediately applied to the instrument. As soon as we change the parameters of one channel, the other channels automatically reflect the changes because the sum of the three channels have to be 100%.

We can also activate or deactivate each channel. For instance we can stop the mass flow rate for channel 2. As we can see the mass flow rate goes down to 0. Now we are only mixing the gases provided from channel 1 and channel 3. We can also stop channel 3 and channel 1. To stop gas mixing click on the conveniently labeled button "stop flow."

Gax Mixer Manager Software Part 2

Now it is time to review the last part of this tutorial regarding the Gas Blender 100 series.

In order to change the configuraton of the gas mixing instrument click on the button labeled "gas settings". In this menu we can choose between different options. Each line corresponds to a specific channel on the gas blender. For each channel we can change the associated graph color.

Here we can check the range of each channel and what it was calibrated for. As you can see in our example, each channel is calibrated on 200 sccm. Gas calibration is indicated with a double asterisk but you can even choose between a list of different gases by means of correction factor.

Here we can change the balance gas. Default is set on channel one. We can even block or unblock a specific channel on the gas mixer if we need a gas mixture composed by less than three channels.

How to Mix 3 Gases Dynamically with One Device

This video shows how you can reduce the number of gas mixing devices you need in order to mix non-aggressive gases by using the MCI gas blender.

You also will see an experimental set up of the gas blender hooked up to three gas inputs.

Finally you will see a list of some of the gas mixing applications that you can use a gas blender for.

Introducing the Revolutionary Gas Blender 100

The Gas Blender Series 100 was specifically designed for laboratory use to control and blend gas micro-flow.

The Gas Blender 100 series is a gas mixing instrument specifically engineered to create and manage 3 gases mixtures dynamically, starting form non-agreesive gases.

The instrument comes bundled with the gas mixer manager, a software specifically designed to manage the gas blender which allows users to easily and dynamically manage gas mixtures.

The Gas Blender 100 series is a high precision gas mixing instrument. Thanks to an 18 point space calibration curve, we can guarantee that each gas mixing channel has an accuarcy setpoint up to 1% with a response of 50 milliseconds to set point change which is currently the fastest on the market.

The gas mixing channels are normally calibrated from 0 to 200 ccm but the range can be either decreased or increased up to 500 ccm if necessary.

Tour of the Gas Blender 100

Now let's examine the contents of the Gas Blender 100 package: it contains the instruement, the power supply, the USB cable, and connectors for the inlet of the gases and the outlet of the gax mixture, the gas blender instrument manual and the cd rom containing the gas blender instrument driver and the software gas mixer manager.

Now let's examine the gas mixing instrument. On the gas blender front panel we can find four push in connectors -- three for the gases inlet and one for the gas mixture outlet. We can also find the power light which indicates the power is on.

It is a time to rotate the gas blender instrument in order to take a look to the rear panel where we can find the power supply block, the on/off switch, the usb port to connect the gas blender instrument to the personal computer, and the BUS RS485 connector which allows connection of up to 64 gas blenders together to reach a gas mixture with high dilution factor

Gas Blender Easy Set Up

Now let's review the Gas Blender installation.

Connect the gas cylinder outlet to the check valve.

Warning this valve only allows one flow direction as is displayed by the arrow and the gas blender valve has to be installed
in agreement with the flow direction

Then take one of 50 cm tubes bundled with the gas blender and connect it to the check valve.
