HKL-AFS spectrometer for Determination of As, Hg, and Se in Domestic Waste
Overview
The HKL-AFS spectrometer for the determination of As, Hg, and Se in domestic waste features an optimized optical configuration that narrows the excitation angle between the light source and the photomultiplier tube (PMT). This optimization increases the emitted fluorescence intensity collected and reduces background noise, thus greatly enhancing the analytical sensitivity of the system.
A semi-transparent door made of ABS that is resistant to chemicals and uses a magnetic seal is isolation the measurement chamber from external airflow disturbances very effectively, allowing reaction processes monitoring visually in real-time. By implementing an independent channel control module, it is possible to avoid cross-talk between detection channels during simultaneous dual-channel operation while ensuring reliable performance even when the concentrations of the two target elements differ substantially.
The technique was developed especially for laboratories that have high-throughput demands and need dual-channel measurement capability; it integrates innovative hardware and software to provide accurate, safe, and user-friendly analysis.
Technical Parameters
Sample Atomization
1) Atomizer: Hydride Generation Shielded Atomizer
2) Carrier Gas/Shielding Gas: Argon
Sample Preparation
1) Vapor System: The newly designed intermittent flow vapor production system is residue-free and allows higher reaction efficiency.
2) Hydride Generator: The hy- generator is a novel high-efficiency titration-type two-stage chemical vapor reaction/separation device. It is capable of achieving complete reactions besides superior gas-liquid separation. It is an ideal choice for complicated samples such as air/soil.
3) Peristaltic Pump: 6-channel pump featuring two pressure-adjustable tube clamps (software adjustable).
4) Exhaust System: Patented pressure-balanced waste drainage (no additional pump required).
Optical System
1) Design: Short focal length optics, non-dispersive in nature, sealed with integrated optics
2) Dual Channel: Simultaneous measurement
3) Light Source: Hollow cathode lamps equipped with instant-on technology; automatic lamp recognition along with real-time status and lifespan monitoring.
4) Detector: Imported photomultiplier tube
5) Linear Range: ＞3 orders of magnitude
Autosampler
1) Sample Introduction: Patented continuous flow injection technology
2) Time needed: Three times measured per sample need only 30 seconds.

FAQ
Q1: What is the smallest quantity we can order? And what is the time frame for delivery?
A: The minimum order quantity is one piece, and delivery will be about 20 days after advance payment.
Q2: What are the advantages of the product?
A: The HKL-AFS spectrometer for the determination of As, Hg, and Se in domestic waste features an optimized optical configuration that narrows the excitation angle between the light source and the photomultiplier tube (PMT). This improvement not only increases the fluorescence intensity accumulated but also reduces background noise, thus making the sensitivity of the analysis significantly better. The combination of a semi-transparent, chemically resistant ABS front door and magnetic sealing creates a tight barrier for the measurement chamber against air flow disturbances from outside, while visually monitoring reaction processes in real time remains possible. Using independent channel control modules prevent channel crosstalk when working simultaneously in dual-channel mode, allowing the detection channels to function effectively even in case the concentrations of the two target elements are very different.
Q3: What sort of after-sales support can I expect from you?
A: We strive to supply a thorough and dependable after-sales support network for you during the whole lifespan of your device. That involves a skilled customer service group ready to make sure your questions are handled without delay, knowledgeable technical engineers who can do remote diagnosis to quickly fix problems, plus continuous online training. We are not just a help desk, we want to be your lab friends you can trust.
Q4: Significance and use of HKL-AFS for Determination of As, Hg, and Se in Domestic Waste?
A: The system is especially designed for laboratories with high-throughput and dual-channel measurement needs. It merges the most recent hardware and software innovations to guarantee precise, safe, and user-friendly analysis. Besides, the streamlined design goes further to ease activities like maintenance, thus lowering complexity and downtime.
