which has the dimensions of a standard SEM. Can anybody recommend a
manufacturer or can recommend homemade solutions?

I have had some success reducing the vibration evident on my SEM by making
four pads from Sorbathane. I used a fairly stiff number of Sorbathane about
3/8 inch thick and cut four pads about four inches square. The shop made me
eight steel plates to go on either side of the Sorbathane and I put these
under the corners of the column section. The vibration on my SEM (from being
on the fourth floor) went down about half. It may not be enough for Auger
but it is inexpensive. TMC, who advertises in most JMSA journals, has a full
set of platforms. Phone:508-532-6330, fax:508-531-8682. I have no experience
with their service.

Controls in a wide range of load handling capacities. The trade name
is Stabl-Levl. I used these to successfully isolate a heavy FTIR unit
that was sensitive to vibration. Unless you can attach them directly
to your instrument, however, you will still need a stiff plate to set
it on with the pneumatic mounts between the plate and the floor. The
address and phone # I have for Barry Controls is:

Haven't ordered from them in a few years, so you might need to check
it if you can't connect. Disclaimer: I have no interest in Barry
Controls other than being a satisfied customer.
