OPA 200 metal original position analyzer

Introduction

OPA-200 metal -situ analyzer is the world's first instrument for fast analysis of metallic materials in the composition and state over a large area of the quantitative distribution , with segregation analysis, quantitative analysis and distribution analysis of inclusions , metal surfaces porosity analysis and component analysis of the four basic functions. Compared with the conventional technology, sample preparation is simple, accurate, rapid analysis of the salient features

Working principle

In situ analysis (Original Position Analysis, OPA) is a technology for the original state of the object to be analyzed the chemical composition and structure analysis. In the metallic material over a large area , the use of digital single discharge spark spectroscopy analytical techniques , through the non- pre-combustion , the excitation spectrum of the scanning signal is continuously generated by spark discharge for direct amplification and high speed data acquisition , whereby the sample surface at different locations chemical composition and content and the structure information of the original surface state, so as to realize the state of the sample composition and quantitative analysis.

Features
Sample holder using scanning platform to achieve continuous movement inspired by the high-speed data acquisition system every spark of spectral intensity and location , digitally recorded in real time , through statistical analysis in order to carry out the sample composition analysis, elemental distribution analysis ( segregation analysis ) , porosity analysis, and distribution of inclusions analysis . This new method of analysis is called a single spark discharge digital analytical technique , referred to as SDA (Single Discharge Analysis).

pletely overcome the traditional chisel point sampling error caused

Analysis of the statistical distribution of sample components
Metal components in situ analyzer has a statistical distribution analysis, statistical analysis can be performed on the elemental composition range surface within a certain area on the sample , rapid, accurate , quantitative , more comprehensive characterization of segregation status . In the display of quantitative elemental composition of the sample distribution , while matching the specified content automatically calculate the interval ( such as C at O.18 ~ 0.22%) proportion of the total area within the analysis area or at a specified level of confidence ( such as confidence level 95% ) , the statistical distribution of the content of each element
