Sulfur analyzers
Based on the worldwide longest tradition in the analysis of the
elements CHNS and O Elementar has developed a sulfur analyzer (Rapid S cube) which combines highest
analytical performance with automatic sample throughput. The sample
handling by pelleting or use of tin capsules and fully automatic
injection into a high temperature combustion zone is typical for
our elemental analyzers. The fast and sensitive SO2 determination
by means of IR detection is specific to the requirements of sulfur
analysis, e.g. in coal. It is characterized by special sensitivity
and easy handling.
The requirements for lowering the detection limits for sulfur in
gasoline, diesel and other hydrocarbons are becoming more and more
stringent. vario TRACE
S liquid injection has been developed to meet the industries
needs for high precision at the lowest concentration levels. New
patent pending technology results in a lower detection limit of
approx. 10 ppb. The vario TRACE S analyzer utilizes combustion with
UV fluorescence detection according to ASTM D 5453 and D 6667 DIN
ISO 20846 (draft).
The elements sulfur and nitrogen are found in low concentrations
in hydrocarbons such as gasoline, diesel or natural gas. vario TRACE S/N liquid injection is a
new concept for an analytical combination instrument. Two complete
separate combustion and detection channels are incorporated into
one analyzer, sharing just the liquid automatic injector (making
two separate injections) and electronic control and processing.
This allows the ideal analytical conditions and catalysts to be
used for each analysis without any compromise. It also results in
significant cost and space savings compared to two separate
analyzers. The methods are according to ASTM D 5453, D 6667, D 4629
and DIN ISO 20846 (draft). Trace analysis with safe and fully
automatic operation.
