Pulse furnace

笔记: not greater than the sample standard deviation or uncertainty shall prevail.

2, 发动机: the modulation system adopts single-chip microcomputer control of high-precision stepper motor, to achieve long-term stability of the modulation frequency;
3, 光源: infrared light source selection of efficient, long-life precious metal micro-infrared luminescent and gold-plated metal mirror;
4, 恒温: the whole gas chamber for constant temperature control, to ensure the analysis of constant temperature, 确保测量精度, the use of temperature compensation semiconductor detector, to ensure that the instrument by the outside influence is small, the baseline is very stable.

2, pulse electrode furnace heating temperature is high, using program control power, can provide constant power heating, slope heating, segmented heating and other program heating methods, improve the analysis accuracy. It is suitable for rapid analysis from low melting point materials such as aluminum alloy to high melting point materials such as tungsten alloy. The electrode is suitable for a variety of types of crucible, according to the release of different samples, can choose a variety of crucible including sleeve crucible, high temperature crucible, effectively reduce the user’s use cost. The electrode cooling system adopts a single cycle independent cooling system, which can directly connect the circulating water or the external water cooling device, and has the characteristics of good cooling effect and high reliability.

2, the design of the sampling system is open, its advantage is that the pollutants are discharged from the top of the furnace, not into the system, 易于操作, the system sealing requirements are not high.(Closed, the gas path through a costly six-way valve to control, internal out.(Some companies have complex sampling device, there are two cylinders, such as the sample stuck, need to open the cylinder, difficult to take out). The micro-flow sensor is used to achieve high precision flow control, and the influence of analysis air flow changes on the analysis is minimized. Gas conversion through this valve, so that the valve is easy to break, dust and other pollutants are also easy to bring into the system). This injection device is simple and can be automatically injected, in case the sample is stuck, easy to remove

2, multi-point correction: with multiple analysis results correction
3. Blank correction

2. Other power supply of the instrument: 220VAC 10%, 501赫兹, maximum current 10A.
3, circulating water power supply: 220VAC 10%, 501赫兹, maximum current 16A.

2. Automatic storage of analysis results;
3. The sample weight is automatically entered into the software;
4. Channel setting is optional;
5, dynamic release curve drawing and storage, 卸载;
6, the analysis results of a variety of correction modes, can be manually corrected, can also be corrected through the analysis results; Can be single point correction, can also be multi-point correction;
7, the data screening, average, standard deviation, relative deviation, ETC。;
8, the new software can be based on user application, can design a number of calibration lines, greatly facilitate the use of users;
9, the host can and computer, 打印机, electronic day equal connection to achieve data transmission;
10. The analysis time and blank value can be adjusted, and the blank value of the melting agent can be automatically removed;
11, the user can store several analysis methods for different analysis samples.
12, can store a lot of sample weight (quantity is limited only by the computer hard disk capacity).
13, can output regular format results report.
14, can be connected with the user database, to achieve remote transmission of analysis results, easy to achieve the network management of analysis results.
15, can quickly carry out instrument blank determination.
16, sample number can be stored and edited.
17, can be applied to automatic sampling, to achieve automatic operation of the instrument.
18, oxygen can be arbitrarily set up high and low analysis channel to meet the analysis requirements of different content and different materials. Users can use the combination freely according to actual needs.
