ICP inductively coupled plasma mass spectrometer
1, the main configuration and accessories:
Based on photomultiplier PMT detector of single channel scan inductively coupled plasma emission spectrometer, high-frequency generator, automatic tuning, provide both Chinese and English operation interface of the software;
Private automatic temperature circulation cooling water system;
Argon gas.
Cooling water pipe;
High sensitivity sample system (high import type atomizer with binocular atomizing chamber)
2, main technical parameters:
Desktop, plasma vertical observation system.
Plasma flame can be adjusted to 2 d (control) by computer, and use the "instrument diagnosis" function, adjust the real-time observations.
Precision: better than that of national verification regulation grade A standard
Stability: is superior to the national grade A standard test procedures
High resolution: in Mn257.610 nm, half peak width for 0.008 nm or less (3600 line grating).
0.015 nm or less (2400 line grating).
All elements meet the national standard grade A standard, some elements such as Ba detection limit is far lower than the national grade A standard
Line flexibility: line of analysis element may be qualitative, semi-quantitative and quantitative analysis. With thousands of spectral lines, can choose the appropriate line according to needs and interests, to avoid possible interference, to provide you with more choices, more reasonable recommendation, let the test to become more professional and accurate.
3, sampling system:
Torch pipe: one-piece. According to the center channel size optional a variety of models
Atomizer: efficient import atomizer, many types of optional, high salt, HF resistance, etc
Atomizing chamber: double barrel type atomizing chamber, can be equipped with swirl atomizing chamber
Always argon consumption: argon gas consumption is less than 14 l/min
Peristaltic pump rotation speed can be set up according to the demand flow rate adjustment (namely according to the sampling speed setting, intuitive, accurate)
4, rf generator and plasma:
Type: solid rf generator, water cooling, automatic tuning, various security with overload, over temperature protection.
Output power: 800 w ~ 1600 w, continuous adjustable, the accuracy of 2 w
Open and plasma gas, auxiliary gas and carrier gas flow for the software control, ignition, fire fighting are also controlled by the software.
5, optical system:
Optical stability, and sampling system design on a platform, the entire optical system with anti-shock measures, general analysis of the ground vibration does not affect the performance. The instrument stable MATS to add a set of anti-shock protection, have the purpose of the secondary shock.
Temperature stability: plus or minus 0.1 ℃.
The minimum interval is 0.0004 nm
6, control software:
Software is easy to operate, intuitive, with functions of qualitative and semi-quantitative and quantitative analysis, the optimized function of instrument diagnosis, software is all Chinese, can choose according to need to switch. Report format output format to PDF, excel, electronic file or print directly, and for Chinese template. Control software can run under the Chinese version of Windows 7 and XP run under. Software with automatic sampler control interface.
Analytical spectral lines, has the function of spectral line trace, background subtraction; Curve fitting: measuring means has peak height and peak area of two different choice;
Analysis parameters: according to the different spectral lines to select different integration time, the negative pressure, scanning interval, attenuation values.
Analysis parameters: each line measurement wavelength calibration automatically in real time, to ensure accurate measurement of peak position.
Automatic attenuation: each line can automatically decay.
Automatic protection function, communication and control instrument adopts the control card, observation position by software control and optimization, with functions of control peristaltic pump speed. With tianrui AS100 combining automatic sampler, the control switch of samples, such as cleaning, filling process.
Instrument diagnostic software and network communication, data processing, automatic generation of test report.
Software with functions of data file management, support data backup, restore, delete, support a textual format for data output. Format optional class, also can print output.
