Main features and software functions
- excellent optical systems, advanced control system: to ensure accurate positioning, good signal-to-background ratio
- imported key components: ensure instrument accuracy and sensitivity;
- Minimum Matrix effect: 99% of the sample without matrix separation;
- Wide measuring range: analysis from Ultra micro to constant;
- Multiple elements analysis: 72 kinds of metal elements and some non-metallic elements can be analyzed,;
- Can do qualitative or quantitative analysis;
- Convenient analysis software: Based on the Windows XP platform ,the third generation of Chinese or English operating software, making it easier to operate easily, without having to install, software can be used directly, the data processing system to provide a variety of functions, output data can be arbitrarily selected and print.
Unique software advantages
| Independent research and develop software with company logo | Increase the standard addition method |
| Based on windowsXP, windows7 windows8, the third-generation multi-window analysis software in English and Chinese | Integral ways: single-point fast, multi-point average, Gaussian curve |
| multi-window and multitask can do simultaneously | Test methods are: routine testing, normalization, coefficient calculation, standard addition method |
| Default best analysis mode (no need modification or writting by the analysts),rapid scanning speed, support for laser printers, arbitrarily select the analysis result needed print, and can be printed at the same time. | More user friendly (arranged by analysis step -from left to right – from top to bottom) |
| Note: ICP as a large precision inorganic analytical instrument, its software operation and hardware of the instrument itself are the same important. The software without company logo is the earliest one , can not be upgraded ,the operation speed is the slowest and few function. It is the theft of my company’s software. | |
