Technical parameters of PerkinElmer AAnalyst atomic absorption spectrometer

1. Wavelength range: 189－900nm

2. Fully compatible with domestic hydride generators and lamps, Winlab 32 software can calculate peak area and peak height. Using domestic hydride generators and As lamps to measure the standard curve of arsenic, the standard solution concentrations of arsenic are 2, 4, and 6 ppb, respectively, with a linear coefficient better than 0.9999.

3. FIFU function: It has the function of combining FIAS with graphite furnace, and can automatically perform online pre concentration of elements. The process of hydride generation is not affected by the reduction rate, and the sample can be analyzed directly without prior reduction. The detection limits for direct analysis of As (V), Sb (V), Se (IV), and Hg (II) are at the ppt level.

Characteristics of PerkinElmer AAnalyst Atomic Absorption Spectrometer

1. The width is automatically selected, and the height of the slit is automatically selected.

2. Detector: Full spectrum high-sensitivity array type multi pixel point CCD solid-state detector, containing a built-in low-noise CMOS charge amplifier array. Simultaneously detect the sample beam and reference beam.

3. Lamp selection: Equipped with two built-in lamp power supplies, it can be connected to hollow cathode lamps and infinite discharge lamps; By using WinLab32 software, the selection and automatic alignment of lamps can be controlled by a computer, which can automatically recognize lamp names and set recommended lamp current values.

Combustion system: Adjustable universal atomizer, high-strength inert material premix chamber, all titanium combustion head.

Drainage system: The drainage system is pre installed for easy detection at any time..

4. Flame injection system: The flame system has the function of direct injection of suspension, which can directly analyze suspended milk powder, etc., and has practical applications.

5. Graphite furnace: The internal and external airflow are separately controlled by a computer. The protective airflow outside the tube prevents the graphite tube from being oxidized by external air. As a result, the lifespan of the tube is extended, and the internal airflow removes the vaporized matrix components from the drying and ashing steps outside the tube. The opening and closing of the graphite furnace is controlled by computer pneumatic control to facilitate the replacement of graphite tubes.

6. Power supply: The graphite furnace power supply is built-in, and the entire instrument is integrated as a whole.

Temperature control infrared probe for real-time monitoring of graphite tube temperature, with voltage compensation and graphite tube resistance change compensation functions.

7. Graphite tube: The standard configuration is an integrated platform (STPF) pyrolytic coated graphite tube.

8. Graphite furnace injection system: The graphite furnace injection system has the function of direct injection of suspension, which can directly analyze fruit wine, fruit juice, edible vegetable oil, suspended milk powder, etc., and has practical applications.

9. Combined use: Both flame and graphite furnace have compatibility with FIAS FIMS、 Functions and interfaces for the combination of gas chromatography (GC), liquid chromatography (HPLC), thermal analysis (TA) and other instruments. FIAS is used in conjunction with ultraviolet radiation and has analytical functions for nitrite and amino acids. Capable of indirectly analyzing sulfate ions, phosphate ions, and chloride ions.
