The most commonly used instrument
for analysis is the GBC Optimass 8000 ICP-TOF-MS. This system is ideal
for rapid transient analysis of a large number of elements. |

A specialty of this group is sample introduction
by electrothermal vaporization. These are generally rebuilt graphite
furnace systems for graphite furnace AA. Seen here is a complete system,
including the temperatrue control and electronics system, the autosampler,
and the actual furnace workhead. This is rebuilt from an old GTA-95
GFAA system.

 |
The use of an autosampler is generally needed
due to the very small volume (10 microliters) of liquid that must be
precisely injected for most analyses. |
 |
Though the electronics required to power the
ETV are large, the actual furnace (seen here) is actually quite small. |
 |
Much of the atomic spectroscopy for our experiments is still performed on a standard flame atomic abosrbiton system (FAAS). |
 |
Some experiments are based on electrochemically alterable poplypetides, so we have a variety of electrochemical equipment. |
