Introduction

Key points of standard update and technological evolution

Technical elements	2009 version of spectrophotometry	2022 version of ultraviolet fluorescence method
Detection principle	Nickel-aluminum reduction-colorimetry	High temperature pyrolysis + fluorescence detection
Maximum detection limit	30mg/kg	100mg/kg
Analysis time	90-120 minutes	5-10 minutes

Technical requirements for testing instruments

Key equipment must meet the following requirements:

UV fluorescence sulfur analyzer Equipped with a 1050℃ high-temperature cracking furnace and an online drying device
Spectrophotometer should use a 667nm dedicated detection module and quartz cuvette
Uniformly equipped with GH3039 nickel alloy reaction bottles (resistant to 5mol/L acidic environment)

Quality control implementation plan

Abnormal handling procedures

When the repeatability>RSD10%:
① Check Whether the content of nickel-aluminum alloy meets the 50±5% standard
② Calibrate the empty adsorption value of isopropanol reagent

Fluorescence signal attenuation processing: clean quartz tube + update drying film
