Total Sulfur Analyzer

Product catalog summary

Overview: The TAPI Model 108E is an advanced instrument designed to measure Total Sulfides (TS) in air or carbon dioxide (CO2) gas. It utilizes a modified M100E UV Fluorescence SO2 Analyzer and a M501TS high temperature thermal oxidizer to convert sulfur compounds into SO2 for measurement.

Specifications: The Model 108E offers a range of 0-50 ppb to 20,000 ppb as SO2, with user-selectable units in ppb, ppm, µg/m3, and mg/m3. It features low zero noise (<0.2 ppb RMS) and span noise (<0.5% of reading RMS above 50 ppb), with a lower detectable limit of 0.4 ppb. The analyzer maintains stability with a zero drift of <0.5 ppb/24 hours and a span drift of <0.5% of reading/24 hours. It operates within a temperature range of 5 - 40˚C and has a sample flow rate of 650 cc/min ±10%.

Features: The Model 108E includes auto-ranging, dual range selection, continuous self-checking with alarms, and adaptive signal filtering. It supports remote operation via dual bi-directional RS232 ports, with optional RS-485 or Ethernet connectivity. The instrument also provides digital status outputs and internal data logging capabilities.

Performance: The analyzer achieves a minimum conversion efficiency of 98% for H2S and 90% for COS and CS2. It has a lag time of 20 seconds and a rise and fall time of <120 seconds to 95% of full scale. Linearity is maintained at 1% of full scale, with a precision of 0.5% of reading.

Components and Accessories: The Model 108E package includes a modified M100E UV Fluorescent Analyzer, M501TS High Temperature Thermal Converter, pump, auto-ranging capabilities, and a 47mm particulate filter. Optional equipment includes rack mount brackets, 4-20mA outputs, Ethernet port, and an internal zero/span option with H2S permeation tube. Accessories available are RS-232 cables, expendables kit, and spare parts kit.

Ordering Information: Customers can specify input AC voltage and frequency (100V-115V, 50Hz or 220V-240V, 60Hz) and output DC voltage (10V, 5V, 1V, 100mV). Additional options include a multi-drop RS-232 connection and an external M702 calibrator for blending H2S span gas with process CO2.
