I have a Teledyne trace oxygen analyzer Model 306WA. What is the life expectancy of the Cell? I also need information for purchasing the solution of 10% Potassium Hydroxide in Distilled Water. I mostly run Argon, Nitrogen and Helium through the analyzer.

Argon gas is colourless, odourless, non-toxic, non corrosive and non-flammable. Argon occurs naturally in the atmosphere, making up about 1% of the air we breath. It is about 30% less thermally conductive than air and is therefore used in sealed units to reduce heat loss or heat gain. Argon is most commonly combined with Low-E glass and replaces the air between the two panes of glass in sealed units.

Yes, most mass flowmeters have outputs of either 0-5 VDC or 4-20 mA. To monitor total accumulation, connect a totalizer/monitor with a matching input ( 0-5 VDC or 4-20 mA).

This is possible as long as the mixture is not too complicated. Contact our applications Department for pricing and availability of gas mixture calibrations.

Yes. In order to use a doppler flowmeter, the liquid must have particulates or bubbles. Most require a minimum size of 25 ppm or 30 μm; check with each doppler flowmeter for specific particle size requirements.

Argon is a safe odorless, colorless, non-toxic, non-flammable insert that is commonly used in place of air between the glass panes of an insulated Low E glass unit. Argon's heat conductivity is lower than that of air. And thus it is better insulator and contributes to a lower U-factor. Argon is not an effective solar performer by itself: that is why it is only used on conjunction with Low E insulated glass.

Low-E stands for "low-emittance", it's a special coating applied to windows that diminishes heat transfer and saves your heating and cooling bills. Argon gas is injected between panes for heat efficiency; since argon is much heavier than air, it's more difficult for warm or cold air to pass through the windows.

I usually don't bother with the E2 correction for a first look at the data. Then, if I see problems with the background subtraction, such as differences in the background subtraction for different reaction channels (e.g. 4n undersubtracted, 5n oversubtracted at around 1.4 MeV) then I try using the E2 correction. The bottom line is: If it helps, use it, otherwise not. Sometimes it can make things worse rather than better. Don't be afraid to experiment.

Yes, you can use any number of gases in your mixture. The instruction manual gives simple math to determine the linear "k-Factor" to apply to the reading if you purchased your meter for air and use it for a mixture of Nitrogen and Argon as an example. Feel free to click the Technical tab on the left to download the instruction manual that gives very good examples.

No...the license to use Atmosphere is on a per-person (single user) basis. They would need their own copy of Atmosphere to use it on their computer.

It depends on the observation, but we have background systematic errors within roughly 5% in the 15-40 keV band if the data have a few x 10 ks exposure.

It depends on the observation, but again we have background systematic errors within roughly 3% in 50-100 keV band if the data have a few x 10 ks exposure.

Nitrogen or air is fine. It just can't have any CO2 in it and should be dry -- less than 0 DegC dew point.

Yes. If a correlated flow tube is used, different flow rates can be attained by using different floats, i.e. carboloy, stainless steel, glass, or sapphire.

If you're just starting out, we recommend sticking with the woods that have traditionally been used for your instrument, purchased from a reputable dealer who has experience in supplying woods to instrument makers. Bear in mind that the biggest investment in your instrument will be your time, not the cost of materials.
