Product description, Technical parameters and configuration

20 years of XRF Research Experiences, Professional design for detecting of Environmental Heavy Metals!

Environmental Heavy Metal Online Analyzer (EHM-X100), which utilizes the patented technology of Skyray Instrument --- X-ray fluorescence (XRF) nondestructive testing technology, in perfect combination with the environmental particulate matter (PM) automatic deposit technology, is well in compliance with USA EPA Method IO-3.3. By using the core technologies such as the unique X-ray source, the sample excitation structure, the detection system, the PM automatic deposit and automatic sample changing system, the EHM-X100 system has greatly improved its detecting sensitivity of atmospheric heavy metal particles, and can accordingly realize the detection of low-content heavy metals such as Pb, Cd, Cr, As, etc.. Furthermore, it can also achieve the continuous automatic monitoring with long-term (1 to 3 months) unattended operation.
So far, EHM-X100 has been referred to Kunshan Environmental Monitoring Station, Suzhou Environmental Monitoring Center, Jiangsu Provincial Environmental Monitoring Center and China National Environmental Monitoring Center, respectively, to carry out the environmental technology verification according to the agreed test plan. In addition, we have signed an alliance protocol with a French professional environmental technology company – ARIA TECHNOLOGIES, to promote the environmental heavy metal monitoring system.

Configurations

Core Analyzer

The analyzer consists of particulate matter (PM) automatic sampling system (particulate matter cutter, DHS dynamic heating device, flow measurement device, sampling pump), sample changing system (reel-to-reel PTFE membrane tape sampling, tape transport plate), XRF analysis module (X-ray tube, X-ray detector, digital multichannel analyzer, FP algorithm analysis software), and control system (sampling control, membrane tape transport, XRF detecting, flow record and control, calculation of pollutant concentration, result display, etc.). These four systems, excluding PM cutters, are integrated in a single cabinet, convenient for installation and transportation.

Heavy Metals Workstation

Hardware:
(1) User can deliberately choose from 5U ultrathin integrated industrial computer (with 10’’ touch screen and various expansion ports) and 15’’ touch screen controller (with height of 10U on 19’’ cabinet), whose basic configurations are at least dual-core CPU 2GHz, with RAM over 2GB and Hard disk over 8 GB.
(2) Interface: input/output interface 24VDC, 2A, RS232 serial port (Modbus protocol, max. 38.4k bps); the internet interface connects between the workstation and the analyzer, to which guarantees bulk data transmission.

Software: 
(1) EHM-X100 control and comprehensive analysis software supports both Chinese and English interfaces and touch screen operation, displays information like real-time sampling flow rate, sampling time, measuring status, heavy metal concentrations, concentration curves. It also has the functions of self-diagnosis and setting, real-time condition monitoring, with large storage space for over 10 years of monitoring data. With application of the advanced hierarchical modular design, the system possesses functions like data setting, calibration, saving, display, query, analysis and communication.
(2) Through open communication protocol, user can access data collection platform to network with provincial and national stations.
(3) The saved monitoring data files can be exported in TXT or EXCEL. The software saves energy scanning spectrograms of each measurement and calibration, and supports retrieval and query.

Particulate matter cutter
TSP, PM10and PM2.5 cutters are optional to realize the measurements of heavy metal particles with different aerodynamic sizes. Meanwhile, outdoor temperature sensor is also equipped, with a shutter cover and lightning protective isolator.
It is also equipped with roof fitting, which can mount the cutter on roof. Users can choose vehicle-mounted platform making cutter fixed on car roof.

Sampling pump
A highly efficient diaphragm pump is adopted with maximum flow rate of 168 L/min and the minimum vacuum pressure of 60 Torr.
