General specimen weighing: Recommended 80 ~ 100mg

Power source: AC220V ± 22V

Total power: ≥4000W

Autosampler: Can a single injection 29

Dimensions: 690mm × 750mm × 720mm (W × H × D)

Main features:

■ Technical Features

1, C, H, N three elements measured by independent testing, using the company's proprietary quantitative sampling device to ensure that a single sample analysis time of six minutes. The instrument can be set according to the software element type single sample analysis, such analysis only C, H or three elements are analyzed. Instrument Factory can choose different mode of analysis based on the user, thereby saving the user's cost.

2, autosampler device so happy and relaxed operation.

3, the combustion gas is collected after the first detection, does not require separation of the gas generated by the combustion process is not required for all of the combustion gases in whole detector, thereby to save time and cost.

4. The instrument is equipped with a plurality of pressure sensors, with the gas line diagnostic software functions and correction features to ensure that users are most easy to use instrument.

5, optimization of pneumatic control, design a controlled closed system, with oxygen to purge the system of air and residual combustion gas measurement system (ie, the gas path analysis) seal isolated, eliminating the environment affected.

Patented technology:

A test of the hydrogen content in coal (ZL 200410046810.7)

2. A quantitative sampling gas automatic device (ZL 200720140722.2)

Q:What instrument is used to detect formaldehyde more accurately?
The test principle based on formaldehyde self test box is recommended by the state as a colorimetric method of phenol reagent. Judging from the test results of formaldehyde, the formaldehyde self-test box is semi quantitative testing products, which can fully meet the needs of people to detect formaldehyde concentration in indoor air.
Q:How do you understand the performance indicators of an analytical instrument: dynamic range? How do you understand the following diagram?
In the linear response limit above the measured signal, it is necessary to change the "sampling amount" and other measures, so that the measured signal in the linear range before you can calculate the results reported
Q:What are the skills of purchasing a gas chromatograph?
Qualitative, quantitative, repeatability is mainly to check the stability of the instrument indicators, which is very important for the analysis of samples. The stability of a good instrument should be excellent, which requires repeated sampling, retention time and consistency of content. The results can be convincing.
Q:What is instrumental analysis?
An analysis based on the chemical reactions of substances known as chemical analysis. Chemical analysis has a long history and is the basis of analytical chemistry, also known as classical analysis. Chemical analysis is absolute quantitative, according to the amount of the sample, the amount of the reaction product or the amount of reagent consumed and the stoichiometry of the reaction, the quantity of the component to be measured is calculated.
Q:How to analyze the instrument and select the regulated power supply
In the power supply voltage to provide a stable premise, but also consider the change of load rate, robustness is power, analytical instruments if there is load or current mutation cases, ordinary power prone to instantaneous voltage drop, affect the measurement results or performance;
Q:How to select multiple elements and analyze the working parameters of the instrument at the same time
1. Analysis method: photoelectric colorimetric analysis2, range: 0-1.999A absorbance value, 0-99.99% concentration value3, measurement accuracy: in line with GB223-88 standards4, measurable elements: metal materials manganese, copper, nickel, chromium, molybdenum, rare earth, magnesium, titanium, zinc, aluminum, iron and so on
Q:What are the biological analytical instruments? It is better to have specific operation and maintenance instructions, preferably the latest instruments
Molecular spectra (UV, IR, MS, NMR, Flu), chromatography (GC, LC), spectrophotometry, laser spectroscopy, Raman spectroscopy, flow injection analysis, polarography, ion selective electrode, flame photometric analysis, etc.
Q:The automatic biochemical analyzer belongs to several kinds of medical instruments
Previously, some registrations were of the three category, and are currently collectively referred to as the two category. Domestic automatic biochemical analyzer which should be the best quality of Nanjing Yi rambe.
Q:About chromatographic instruments
Gas chromatography can be used as a liquid sample.
Q:What are the modes of calibration for measuring instruments?
The theodolite needs to be calibrated, the horizontal axis is perpendicular to the vertical axis, the cross wire is perpendicular to the horizontal axis, and the collimation axis of the telescope is perpendicular to the horizontal axis and the transverse axis is perpendicular to the vertical axis
