It seems the buzz about bio-fuels is growing more intense every day. We would like to provide a resource for those interested in the manufacturing process to visit and learn more about it.

We are also going to provide ''Application Notes' that pertain to Automated Titration Solutions (i.e to determine how much catalyst is needed, etc.)

Please feel free to register and become a part of this resource.

I am having problems connecting the titrator to my pc.  The RS-232C cable is plugged into the correct COM port.  The bit rate, parity, data bit, and stop rate are the same on both the computer and the titrator.  The problem is that the computer will not detect the titrator.  Any one have any suggestions?

 6   General Category / General Discussion / mitsubishi moisture analyser missing user manual

Hi. I have a mitsubishi moisture meter model CA-05/VA-05 but no instruction manual. Can anyone tell me the sequence of key strokes on the instrument keyboard to run both liquid and solid samples. This may be a long shot but does  anyone have a copy of the user manual that I can purchase. I believe the later model analyser, the CA-06/VA-06, may use a similar manual.

WhesseIII, can you help us understand a few of the specifics of your titration by answering these questions?  Send the printout copies to info@scientificgear.com.  thanks.

A: sample name, sample size, not only the oil more detail,,,
B: the method parameter print out copy,
C: result print out copy with the graph and the data list,
D: reagent info., concentration and the name,

I am too having problems using ASTM D664 for oil analysis.  In determining TAN, there should be 2 endpoints. 1) Strong Acid Endpoint. 2) Total Acid Number.  I have the control set up to find 2 endpoints, but it does not stop after finding the second endpoint. Also, the curve that prints out is step like and not a smooth curve. The derivative graph shows a lot of inflection points.  Any help would be great.

 10   Titration Category / Karl Fisher Titration / Re: Karl Fisher in Standby

How quickly do you want to be "ready to go" each time you step up the the Karl Fisher and want to run a test.  If this is important than the other issues are probably not as important.   

Keeping atmospheric moisture out of the cell by either keeping the instrument running or by waiting to turn the instrument on is going to require possibly about the same amount of energy and reagent to bring the vessel to ready mode.  I guess you could experiment with ways of storing the vessel while it is still charged with reagents - in dry places, etc...but I don't know if that will really work.  I guess alternatively you could use an extra reagent bottle to store the in-use reagents and see if that works - problem with this though is you end up mixing up good and old/bad reagents and may waste reagents in the end...

As for the instrument there really is not a problem by keeping it on as the stirrer motor is probably the only mechanical part that stays running....kind of like a fan on a PC.  I don't really think this is a problem though.
