A universal method for the speciation analysis of arsenic in various seafoods
( 19.01.2021 )
A Chinese group of researchers have developed an analytical method for arsenic species that can be used for various seafoods such as seaweed, fish, shellfish and shrimp. Using microwave-assisted extra...

Mercury-binding proteins in tuna and salmon
( 18.01.2021 )
A Chinese group of researchers investigated the mercury-binding proteins in tuna and salmon. More than half of the mercury from fish muscle was found in the soluble protein fraction. Beta-actin was id...

New isotope ratio mass spectrometry system delivers high-precision analysis for a range of applications
( 07.01.2021 )
A new inductively coupled plasma mass spectrometry (ICP-MS) instrument has been designed to enable scientists working in earth sciences, nuclear safeguards, and biomedical research to conduct reliable...

Speciation analysis of Gadolinium-based contrast agents using hydrophilic interaction liquid chromatography hyphenated with inductively coupled plasma-mass spectrometry by avoiding organic solvents
( 02.12.2020 )
A group of Japanese researchers have developed a HILIC separation of Gadolinium-based contrast agents using an aqueous mobile phase. ...

Man made mercury pollution is reaching even deep ocean organisms
( 23.11.2020 )
The sinking carcasses of fish from near-surface waters deliver toxic mercury pollution to the most remote and inaccessible parts of the world’s oceans, including the deepest spot of them all: the 36,0...

Transformation of arsenic species during ultrasonic sample pretreatment
( 17.11.2020 )
A group of Chinese researchers now studied the transformation kinetics of different arsenic species in aqueous solution by ultrasonic treatment in order to select optimum conditions for efficient extr...

New way of cooking rice removes arsenic and retains mineral nutrients, study shows
( 10.11.2020 )
Cooking rice in a certain way removes over 50 per cent of the naturally occurring arsenic in brown rice, and 74 per cent in white rice, according to new research....

New Human Hair Reference Material Supporting the Biomonitoring of Methylmercury
( 16.10.2020 )
An international group of researchers have developed a new human hair reference material for mercury speciation analysis. ...

FDA Approves Inorganic Arsenic Limits in Baby Rice Cereal
( 06.10.2020 )
The Food and Drug Administration announced recently the availability of a final guidance for industry entitled “Inorganic Arsenic in Rice Cereals for Infants" defining an Action Level of 100 ppb....

Speciation analysis by mass spectrometry for studying organotin-protein interactions
( 20.09.2020 )
A group of German researchers from Münster has used the combination of speciation analysis and native mass spectrometry as a tool to study diverse interactions of environmentally relevant organotin co...
