I. Product Introduction

The flame photometer is a relative measurement instrument based on the principle of atomic emission spectrometry (flame color reaction), mainly used to determine the concentration of alkali metal and alkaline earth metal elements (such as potassium, sodium, calcium and lithium) in solutions. The concentration value of the tested sample is a relative value against the concentration of a standard solution under the same test conditions. Before testing, a set of standard solutions must be prepared, then a calibration operation is performed, a standard curve is drawn manually or by the instrument, and finally the tested sample is measured to obtain its concentration value or other required calculation data.

II. Application Range

It can be widely used in pre-treatment requirements for environmental monitoring, agriculture and fertilizer industries, food industry, chemical manufacturing, medical and clinical diagnosis, geological mining and new energy industries.

NY/T 2420-2013 "Determination of total potassium in plants - Flame photometric method"

IV. Features

1. Adopts a 7-inch color capacitive touch LCD screen; convenient to operate, small in size, stable and reliable.

2. Has the function of direct concentration reading for five elements: potassium, sodium, lithium, calcium and barium; able to simultaneously measure 3 elements in any combination.

3. High-transmittance, extremely low stray-light filters reduce background interference to obtain a higher signal-to-noise ratio.

4. One-key ignition function, convenient and fast; uses a built-in silent air pump with no need for an additional air compressor.

5. Uses a self-developed high-performance nebulizer, with uniform and efficient atomization and smooth and stable sample aspiration, ensuring the accuracy and stability of sample analysis results.

6. Can store up to 10 points per set of standard curve parameters, with a total of 20 curve data sets savable.

7. Equipped with a moisture separator to avoid the influence of environmental changes and ensure stable analysis results.

8. Equipped with a flameout protection device, with the function of automatically closing the gas solenoid valve after flameout.

9. Equipped with a single-point calibration function, allowing quick correction when the baseline drifts.

10. Equipped with a historical record printing function and USB flash drive export function.
