H₂S Analyser with Vapour Phase Processor – SA4000-4H₂S Analyser with Vapour Phase Processor – SA4000-4
The H2S Analyser with Vapour Phase Processor (VPP) is a compact bench-top instrument, used to measure the total hydrogen sulphide (H2S) content of fuel oils, such as marine residual fuels, distillates and petroleum blend stocks. The H2S Analyser can measure H2S concentrations from 0 to 250 mg/kg (ppm) in the liquid phase.
Designed with an integrated VPP, components such as toluene, xylene, thiols (mercaptans) and alkyl sulphides are removed to ensure the accuracy of results.
An analytical balance can be connected to the H2S Analyser which reads the data from the balance and automatically calculates the sample mass, saving time and eliminating the risk of data entry errors.
Other enhanced functionality features include real-time graphical display of test progress, custom result reporting and automated gas calibration.
Statistical Quality Control (SQC) software allows analysis of results in accordance with ASTM D6299.
A limit of 2 parts-per-million (2 ppm) in the liquid phase was set by the industry in 2012 under ISO 8217, which made IP 570 Procedure A the referee test for H2S.
IP 570 includes the use of verification fluids as a recommended practice. Participation within a Proficiency Test Scheme (PT Scheme) is stated as the preferred means to achieve this.

Details
Ease of use:
The H2S features a simple user interface with touchscreen display. An integrated camera showing the test vessel aids sample input and ensures the correct amount of sample is used for accurate results.
Cost saving:
Due to the simplicity of test set up and no requirement for analytical preparation by an experienced chemist, low operator time is needed to run a test, helping to reduce labour costs.
The H2S Analyser requires only a small sample volume, helping to reduce cost and waste per test.
As the H2S uses a non-chemical method, no costly or hazardous chemicals are required.
Calibration and verification:
Calibration of the H2S Analyser can be performed in the field, eliminating the costs and time associated with sending the instrument to a service centre.
Service and maintenance:
The rugged design ensures minimal operational maintenance in needed.
*Subject to maximum one pack of 100 per instrument. Serial number is required.
