Reduced Cost of Ownership and Maintenance

nnThe patented large-volume furnace prevents severe-duty samplesfrom plugging or failing prematurely consequently extending routine
maintenance intervals. A platinum catalyst provides an enlarged
surface area for the oxidation reaction in the furnace. This increases
the lifecycle of the catalyst reducing cost of ownership. nn

Simplified Sample Delivery System

nnInnovative sample delivery system avoids inherent mechanical
breakdown of complicated sample injection mechanisms.
Customarily high temperature analyzers use an injection valve
mechanism,which is prone to fail due to its narrow passages, small
parts and exposed seals.The astroTOC HT has a continuous sample feed by a peristalticpump providing a robust, easy-to-maintain sample injection into the
furnace. This dramatically reduces maintenance cost. nn
