HKL-AFS spectrometer for Determination of heavy metal element in goat milk
Overview
The system has been designed to measure hydride-forming elements, such as arsenic, antimony, bismuth, selenium, tellurium, lead, tin, and germanium as well as atomic vapor-phase mercury and elements like zinc and cadmium that form volatile compounds. This is done through a non-dispersive vapor generation system and it has two detection channels that allow measuring at the same time. The system can automatically dilute very concentrated samples, allow independent calibration curves for each channel, and give channel-by-channel dilution control. Designed for trace analysis, the instrument can be equipped for hydride generation techniques. Through its patented continuous flow injection technology, three times of the same sample measurement are accomplished within half a minute.
Technical Parameters
1. Sample Atomization
1) Atomizer: Hydride Generation Shielded Atomizer
2) Carrier Gas/Shielding Gas: Argon
2. Sample Preparation
1) Vapor System: New intermittent, no residue vapour generation system having increased reaction efficiency.
2) Hydride Generator: A highly efficient titration-type two-stage chemical vapor reaction/separation equipment enabling complete reaction and excellent gas-liquid separation (very suitable for complicated samples such as air/soil).
3) Peristaltic Pump: 6-channel pump with two pressure-adjustable tube clamps (software adjustable).
4) Exhaust System: The unique pressure-balanced design allows for waste drainage without the need of any additional pump.
3. Optical System
1) Design Features: Compact optoelectronic modules sealed and characterized by a non-dispersive, short-focal-length design for better optical stability.
2) With its dual-channel capability, the instrument can perform simultaneous measurements on two separate channels in real-time, effectively increasing throughput and efficiency.
3) Light Source System: Hollow cathode lamps with instant-start technology are installed. The system is capable of performing automatic lamp identification and provides continuous real-time lamp status and lifetime monitoring.
4) Detection System: Utilizes an imported photomultiplier tube for high sensitivity and reliable signal detection.
5) Linear Range: ＜3 orders of magnitude
4. Autosampler
1) Sample Injection System: It features patent-protected continuous flow injection technology that ensures consistent and accurate sample handling.
2) Analysis Throughput: Able to carry out three measurements from a sample in 30 seconds only, making sure it is highly effective and fast.
3) Element Detection Performance
Elements | DL (ng/ml) | RSD | Linear Range |
As, Se, Pb, Bi, Sb, Te, Sn | ＜0.01 | ＜1.0 | over 3 orders of magnitude |
Hg, Cd | ＜0.001 | ＜1.0 | over 3 orders of magnitude |
Ge | ＜0.05 | ＜1.0 | over 3 orders of magnitude |
Zn | ＜1.0 | ＜1.0 | over 3 orders of magnitude |
5. Data Processing System Features
1) Operational Flexibility: Seamlessly switch between offline and online modes during operation.
2) Multi-Tasking Interface: Open single or multiple windows simultaneously for efficient workflow.
3) Database Management: Flexibly connect to and select from single or multiple databases.
4) Enhanced Accuracy: Utilize management sample calibration to improve measurement precision.
5) Customizable Reporting: Design reports with unlimited formatting options and templates.
6) Data Portability: Export all measurement data to Excel for easy modification and analysis.
7) Collaborative Workflow: Support LAN-based data sharing to promote team resource collaboration.
