Elemental Analyzers

EMIA-V2 series Carbon/Sulfur Combustion Analyzer

Overview

The EMIA-V2 series measures carbon and sulfur extracted during combustion in a programmable High Frequency furnace without conversion. Combustion control is achieved through the use of the high-frequency induction furnace method. Appropriate heat-control in accordance with the analysis objective enables high-precision analysis for all types of samples. A variety of models allow you to select the furnace system that is best suited to your target samples and application.

EMIA-920V2 C/S analyzer: High performance analyzers with outstanding accuracy of less than 0.3ppm
EMIA-320V C/S analyzer: Standard performance analyzers for wide range of applications.

Features

"Auto cleaner" mechanism reduced maintenance works
(Standard for 920V, Option for 320V2)
The Dust filter heating mechanism provides stable analysis with extremely low gas absorption
(920V2 only)
Real-time simultaneous detection of CO/CO₂/SO₂ without an oxidizing (CO→CO₂) or SO₃ trapping reagents.
Wide variety of self diagnostics
Programmed temperature curve for optimizing combustion.
Choose from standard or wide range models to suit your application requirements.
