EMGA-921

Product catalog summary

Overview: The document details the EMGA-921, a high-precision hydrogen analyzer for solid materials, used in advanced research, development, and quality control across industries like steel and new materials.

Specifications: The EMGA-921 employs a Thermal Conductivity Detector (TCD) with a measurement range up to 200µg/g hydrogen, sensitivity of 0.0001µg/g, and repeatability of SD≤0.04µg/g or RSD≤0.5%. It features dual sample/flux introduction and an impulse furnace with inert gas fusion. The unit measures 750mm (H) x 785mm (D) x 653mm (W), weighs 230kg, and can be split for transport.

Installation Requirements: Installation requires specific power sources (AC200/220/230/240V ± 10%) and grounding (earth resistance <10Ω). It includes components like a cooling water circulation unit and requires user-provided items such as a PC and printer.

Automation and Operation: The analyzer includes automated systems for crucible loading and electrode cleaning, simplifying operations. The software offers real-time data display, management, automated graph saving, and sample weight registration.

Maintenance and User Interface: A maintenance navigator guides users through consumable replacements and routine maintenance with visual aids. The software interface is user-friendly, supporting easy operation and data management.

Additional Models: Other models, EMGA-821AC and EMGA-821M, offer similar performance but lack certain automated features like the crucible loader and auto cleaner.

Accessories and Options: The document lists spare parts and options, including various crucibles, capsules, an optional electronic balance, and an automatic voltage regulator (AVR).

Procedures: The analyzer features an impulse furnace with inert gas fusion, dual sample/flux introduction, auto cleaner, and crucible loader. It supports calibration using reference gas or standard samples and includes a calibration curve correction function. The system displays real-time extraction curves, allows analysis interruption, and provides self-diagnosis and alarm displays.

Standards and Recommendations: The analyzer operates optimally between 5-35°C, with a humidity level up to 80% RH between 5-31°C, decreasing to 50% RH between 31-40°C. Vibration tolerance is a duplex amplitude of 20 microns and <0.098m/S2 accelerations. Carrier gas should be Argon with >99.995% purity at 0.35MPa, and operating gas can be dry air or N2 at 0.45MPa.

Additional Information: The system includes a separate water cooler unit and can connect with an electronic balance with 1 - 0.01mg sensitivity. The main unit requires AC200/220/230/240V ± 10% power supply, with a maximum power consumption of 12kVA, and the vacuum cleaner requires AC100V with a step-down transformer included. Users are advised to read the operation manual for safe handling, and contents are subject to change without notice.
