Product Description

AA-1800H is a multifunctional atomic absorption spectrometer with two background correction methods, D lamp background elimination and self-absorption background deduction. It is a high precision analytical instrument integrates flame atomic absorption spectrometry (abbreviated as FAAS), and hydride generation atomic absorption spectrometry (abbreviated as HG-AAS), and graphite furnace atomic absorption spectrometry (abbreviated as GFAAS), and atomic emission spectrometry (abbreviated as AES). An auto-sampler is optional to equip with graphite furnace atomic absorption spectrometry. AA-1800H is widely used in geology, metallurgy, mining, petroleum, chemical industry, mechanical, agriculture, food industry, medicine, health, antiepidemic, environmental protection, and other industries. And it is an essential high precision analytical instrument for scientific research institutes, colleges and universities, and related enterprises.

AA-1800H can be used for analyzing metallic elements, amphoteric elements, and alkali elements. It's a high precision analytical instrument with high performance and its determination range can be from ppb to ppt

                      

Our Advantages

• Advanced determination of flame atomic absorption spectrometry

It is developed by experienced professors and senior engineers who are engaged in analytical instrument industry of atomic absorption spectrometry for many years. The background correction with Deuterium hollow cathode lamp can eliminate the interference of molecular absorption in low content determination. The detection sensitivity is greatly improved, and the value is less than 0.015 μg/ml/1%.

• High detection sensitivity and low detection limit of hydride generation atomic absorption spectrometry

The import known-how such as the advanced pneumatic component theory, and high performance hollow cathode lamp guarantees the hydride generation atomic absorption spectrometry performing a high detection sensitivity and low detection limit. For example, the detection sensitivity of Arsenic element is better than 0.08 ng/ml/1%. The instrument precision is also greatly improved.

• Convenient software operation system provides reliable data processing result

The data processing system of AA-1800H is an application of new data processing achievement in the field of atomic absorption spectrometry. It provides reliable data processing result. Meanwhile, the special designed operation software system is advanced and convenient.

• A partly substitution of graphite furnace atomic spectrometry

The atomic absorption spectrometry together with on-line enrichment by the pneumatic flow injection system designed by ourselves can determine some elements and obtain a high sensitivity, that means it is a partly substitution of graphite furnace atomic spectrometry for certain elements. Thus, it not only reduces the testing cost, but also improves the instrument utilization.

• Special designed double-loop power supply for the high performance hollow cathode lamp

AA-1800H uses special designed double-loop power supply for the high performance hollow cathode lamp, which is convenient for lamp adjusting. It not only improves the lamp energy of some element, but also improves the detection sensitivity to several times. And the performance indexes of the instrument such as stability and detection sensitivity are greatly improved.

• Unique micro-volume sampler with constant current pulse

A unique micro-volume sampler with constant current pulse that designed based on the pneumatic component theory is optional to equip with flame atomic absorption spectrometry. The sample volume can be reduced to 0.1 ml, however, there is few influence on the detection sensitivity. And a relative standard deviation about of 1% can be obtained. Thus, it is very significant to medicine and health care industry.

• Innovative detection system

Innovative atomic absorption detection system guarantees the instrument having an excellent stability. For a non-zeeman atomic absorption spectrometer, the detection precision of 0.0001A makes it to be unique.

• USB communication port

The instrument is controlled by the USB port of computer, which is an advanced communication method. User can choose the computer as required, and that is also available for other laboratory use. However, to avoid viruses, please don't use this computer for internet surfing.

Packaging & Shipping

After carefully unpacking the contents, check the materials with the packing list (page 4) to ensure that you have received everything in good condition.

Place the instrument in a suitable location away from direct sunlight.  In order to have the best performance from your instrument, keep it as far as possible from any strong magnetic or electrical fields or any electrical device that may generate high-frequency fields. Set the unit up in an area that is free of dust, corrosive gases and strong vibrations.

Remove any obstructions or materials that could hinder the flow of air under and around the instrument.

Use the appropriate power cord and plug into a grounded outlet.

Turn on your spectrophotometer. Allow it to warm up for 15 minutes before taking any readings. We suggest you then do the Calibrate System with the Search 656.1nm to set the wavelength to the deuterium lamp emission line.
