Dear Isotopologists,

 

Well, the slip was mine, as Chuck Douthitt kindly

pointed out that Varian actually owned MAT from

1967-1981. Clearly, the dementia has set in for

me.

 

I had to Chuckle at the "etwas geschmacklos"

advertisement that he sent me (which I would

shamelessly pass on to you here, but the

listserve rejects attachments - unlike flies on a

dog).

 

Of more interest is the Curt Burnnée RCMS article

that describes the early years. Although for some

of us it was mercilessly not so long ago, I can

remember a talk at the Gordon Conference that

once referred to some less recent work as "...way

back in the '90s!"  hmmmm.

 

Again I can not attach the paper here for your

amusement, but if you would like a copy drop me

an email offline. (Curt Burnnée, 1997, Rapid

Commun. Mass Spectrom 11, 694-707).

 

Best wishes,

 

Michael

>>Hello,                   November 2, 2009

>> 

>>      We have a Varian MAT 250 isotope ratio mass spectrometer (SN#

>>8223).  This instrument was manufactured in December 1979, a year or

>>more before MAT was purchased by Finnigan.  Unlike the subsequent 251

>>model, which used an Apple II computer, our MAT 250 uses a Hewlett

>>Packard 9815a calculator/computer to operate the mass spectrometer.

>>The hp 9815a calculator/MAT 250 system came with a set of programs on

>>DC 100 cassette tapes.  Some of these tapes were pre-programmed by hp,

>>and some were pre-programmed by the MAT factory at Bremen.

>> 

>>      Does anyone still have a Varian/Finnigan MAT 250, or a Hewlett

>>Packard 9815a calculator/computer, or any of the program tapes for

>>this instrument?

>> 

>>      Thank you, very much!
