Prior to the publication of HJ 1453—2026, the standardisation system for the determination of heavy metals in water in China was somewhat fragmented.[more]

As living standards continue to rise, public concern over food safety is growing. A survey shows that 70% of the public consider 'food safety' as the top concern in daily health and safety.[more]

Geological laboratory testing provides vital support for geological research and plays a crucial role, particularly in the exploration and development of mineral resources. Atomic absorption spectroscopy, as an advanced technique for elemental analysis, h[more]

This method is applicable for the determination of chromium in cosmetics, with a minimum detection limit of 0.1 mg/kg.[more]

Copper alloys find extensive application across industrial sectors, particularly in the current high-speed rail construction where they are extensively utilised for circuit line construction. Consequently, the requirements for copper alloy usage within ci[more]

On 15 April 2012, CCTV's Weekly Quality Report programme, in its episode ‘Secrets Inside Capsules’, exposed certain enterprises in Hebei Province using quicklime to process leather waste into industrial gelatin.[more]

Following digestion, the sample is introduced into an atomic absorption spectrometer. Upon flame atomisation, potassium and sodium absorb at resonance lines of 766.5 nm and 589.0 nm respectively.[more]

Flame atomic absorption spectrophotometry is an analytical method based on the selective absorption of characteristic spectral lines by the ground-state atoms of a target element. When a sample is introduced into the flame, compounds of the target element[more]

In recent years, both domestically and internationally, relatively mature analytical methods have been established for the detection and testing of trace elements in foodstuffs, with significant advances also made in sample preparation and data processing[more]

Polyethylene terephthalate, commonly known as PET plastic, has the molecular formula (C₁₀H₈O₄)_n and is produced via the polycondensation reaction of alcohol esters.[more]

The quality of water directly affects people's health condition. Water quality monitoring has become an important part of our environmental protection.[more]

Various limited metal components in food are determined under different spectral analysis with actual samples, in order to achieve the goal of comprehensive application of atomic absorption spectrometry.[more]

We use directly flame atomic absorption spectrophotometry to determine copper, iron, manganese, zinc, cadmium[more]
