Special instructions
The nj-zd880 photoelectric direct reading spectrometer has entered the domestic and foreign markets relying on the excellent technology research and development ability and the honest service concept of the technical center of Nanjing Nuojin high-speed analytical instrument factory; a large number of users have successively used nj-zd880 photoelectric direct reading spectrometer after investigation, certification and performance price comparison with well-known foreign spectrometers, making it a brand spectrometer in the industry.
The nj-zd880 photoelectric direct reading spectrometer has high sensitivity, up to ppm relative detection sensitivity; high accuracy, especially when the content of elements to be analyzed is lower than 0.1%, the accuracy is obviously higher than other methods; it can carry out multi-element simultaneous analysis, and obtain qualitative and quantitative results of dozens of elements in one excitation and analysis at the same time; it is simple, easy to operate and has fast analysis speed, and can complete "furnace" in 60 seconds It has the advantages of low cost, low consumption of expensive chemical reagents and special auxiliary materials, saving argon, basically variable flow rate, and measuring more than 2000 times per bottle of argon; the operation of the analysis software is intuitive and simple.
The nj-zd880 photoelectric direct reading spectrometer adds "one key start" and "one button close" humanized buttons, which can achieve one button start analysis and close in case of emergency. It is safe, convenient and does not damage the instrument. It has incomparable advantages compared with other brands!
Friendly tips: the quotation in Annex 1 is the basic price of single basic 12 channel standard configuration, not the actual purchase price of the user. After receiving the technical data of our company, the Demander shall describe in detail the type, brand, element name and content range of the materials actually to be analyzed and tested by the unit; fill in the corresponding information according to the "basic channel selection table and user required material range" in the technical data, and Fax or mail our company, in order to get more reasonable, more practical configuration quotation!
Part one: (application scope, performance and technical parameters)
Application, performance and description
1. Application scope: Spark direct reading spectrometer is a rapid quantitative analysis instrument for analyzing the composition of ferrous metals and non-ferrous metals. This instrument is widely used in metallurgical, mechanical and other industrial sectors, for on-line analysis in front of smelting furnace and product inspection in central laboratory. It is one of the effective means to control product quality. It can be used for accurate detection of chemical elements in metal materials, and can be used for accurate quantitative analysis of iron-based, aluminum based, copper based, nickel based and other elements!
2. Analysis of matrix number: the composition measurement of Fe, Al, Cu, Zn and other matrix alloys can be configured.
3. Determination of elements: C, Si, Mn, P, s, Cr, Ni, Mo, V, Ti, Cu, Al, W, Co, Nb, Mg, La, CE, B, Pb, Sn, as, Sb, Bi, Fe and other metal, non-metallic and gas elements in metal solid samples can be determined at the same time. The user can select the element configuration according to the actual needs (see Annex 2 for details)
4. Analysis principle: the sample is excited by high-energy pre ignition spark light source, and the characteristic emission spectrum of each analysis element is generated, which is received by photoelectric conversion element; then the detection and measurement are carried out, and the data processing is carried out by computer to obtain the corresponding analytical content. Analysis sample size: the standard is any processing plane with a diameter greater than 20 mm. Customized small sample fixture can be purchased for small sample analysis.
5. Analysis time: depending on the sample type, generally less than 40s.
6. Standard working curve: according to the analysis requirements of users, the working curve is pre made in the factory. Samples with all working curves in accordance with national or international standards shall be excited point by point on the user's instrument, and the interference and background influence shall be deducted, and copying curve shall be strictly prohibited. At the same time, all analysis programs are open to users, and standard samples and control samples are used at any time on site to establish special working curves. Analysis function: daily analysis, brand control analysis, 1-point or multi-point correction, type standardization and control sample analysis, automatic spectral line tracing of optical system, and Realization of optical system calibration. The instrument has diagnostic functions such as vacuum detection and temperature detection.
7. Data processing function: the analysis results can be displayed in different display modes; the analysis results can be stored and printed.
Nj-zd880 spark direct reading spectrometer is widely used in metallurgical, mechanical and other industrial departments. It is one of the effective means to control product quality by on-line analysis before smelting furnace and product inspection in central laboratory.
System composition and index
1. Optical system: (Optics)
The main optical path includes: 2400 line / mm standard imported grating; stable and reliable 750mm focal length Roland circle sewing frame. The folding front light path design makes the light path structure more compact; the design of convenient and detachable light window and entrance slit makes the maintenance and cleaning more simple. The exit slit is processed by German high-precision machining center, including all possible 120 analysis channels for accurate positioning, which can meet the analysis of various basic elements. This design method brings convenience for increasing channels in the future 。
Aluminum alloy integrated optical room and special central air conditioning heating constant temperature design ensure the long-term stability of the optical room system.
According to different applications, the optical room can be in vacuum or non vacuum state.
2. Light source
Nj-zd880 photoelectric direct reading spectrometer adopts all solid state maintenance free excitation light source, which makes the analysis results very stable. Single pulse spark detection technology, excitation light source excitation
