Detail AAS Murah ( Atomic Absorption Spectroscopy )

The Buck Scientific line of Atomic Absorption Spectrophotometers were designed to
utilize the maximum energy of the single beam optical system. This allowed us to build a smaller,
less expensive and more sensitive instrument. Background correction was achieved by inserting
the deuterium lamp directly after the hollow cathode lamp and using variable giant pulse.

Buck Scientific’s 200 series Atomic Absorption
Spectrophotometers are the culmination of more than 25 years of success and experience as a
manufacturer of spectroscopy instruments.
The 200 Series AA’s are powerful, compact and cost effective solutions to all atomic analyses. It has been designed to meet the
performance and flexibility our laboratory requires— now and in the future.
