Introduction

Interpretation of the core content of the standard

This document specifies the standard method for determining the oxygen (0.0010%~0.020%) and nitrogen (0.0010%~0.020%) content in nickel-platinum alloy using the pulse-infrared absorption method and the thermal conductivity detection method.

Comparison of Method Principles

Detection Elements	Principle	Detection Limit	Applicable Content Range
Oxygen	Graphite crucible is melted to generate CO, infrared detection absorption peak	0.1 μg/g	0.0010%-0.020%
Nitrogen	Determination of thermal conductivity by nitrogen loading into thermal conductivity cell	0.1 μg/g	0.0010%-0.020%

Key Operation Points

Sample Pretreatment

Soak in acetone for 5 minutes and then air dry naturally. Weigh the sample accurately to 0.0001 g (0.1g±).

Instrument Calibration

It is required to use 2 or more national steel standard samples (oxygen and nitrogen content 0.001%-0.02%) for calibration. The blank value must be controlled within <0.00005%.

Precision Control

For detailed repeatability limit (r) and reproducibility limit (R) data, please refer to Chapter 10 of the standard. When the oxygen content is 0.0042%, r=0.0024% and R=0.0025%.

Technology Evolution Analysis

Compared with the traditional chemical method, the innovations of this standard are:

Simultaneous determination of oxygen and nitrogen
Adopting modern equipment such as TC-400 oxygen and nitrogen analyzer
The detection limit is reduced to 0.1 μg/g

Implementation suggestions

The laboratory needs to be equipped with an oxygen and nitrogen analyzer with 1 hour stability RSD<2%
It is recommended to verify the graphite crucible blank value regularly
Pay attention to the melting temperature control for samples with high platinum content
