Page 5: Introduction
INTRODUCTION About this Manual The Total Sulfur Operator’s Manual should be used in addition to the Model 330S & 331S Hydrogen Sulfide Analyzer Operator’s Manual. This manual contains a comprehensive overview of Envent Engineering’s total sulfur addition to their hydrogen sulfide (H2S) analyzers as well as descriptive installation and startup instructions. -
Page 6: Warnings And Cautions
Total Sulfur Option User Manual – Revision 1.0 Warnings and Cautions CAUTION: Hydrogen is extremely flammable. Use Caution when handling. CAUTION: Quartz reaction tube is fragile and is removed during shipping, handle with care. CAUTION: Do not apply power or hydrogen to the total sulfur furnace until the reaction tube is installed and leak tested. -
Page 7: Total Sulfur Option Overview
H2S. The total sulfur option involves the addition of a total sulfur reaction furnace (pyrolysis furnace) to a Model 330S or 331s. The furnace converts all sulfur compounds into H2S, allowing the H2S analyzer to read total sulfur as per the ASTM D 4468-85 “Standard Test Method for Total Sulfur in Gaseous Fuels by Hydrogenolysis and Rateometric... -

Total Sulfur Option User Manual – Revision 1.0 Figure 1. Total Sulfur Oven Cutaway WARNING: Quartz reaction tube located in total sulfur furnace ii) Dual Seal maximum working pressure is 2 PSI iii) Leaks are indicated by monitoring the ball in the H2/Sample Flow meter during a pressure test. - Page 9 (9.25” x 60”) without any leaks or calibration runs. Our calculations based on a 200 /min (flow of 2 on a A-157-1 flow meter). Each analysis will run 3 times. Envent suggests that the bottle should be checked at least 10 days prior to estimated end of life.
