In this issue
Welcome to the Inorganic Vision. In this edition, we will show how Na and K analysis can be done easily in cooking oil with direct flame AAS and how to detect arsenic and mercury in ppb level using FIAS-ICPOES. The analysis of milk with ICPMS as well as improving the detection limit of ICPOES with stable sample introduction dual spray chamber will also be discussed. | |

FIAS-ICPOES and Continue Hydride-ICPOES - Improve lab efficiency on hydride analysis
 In our last issue of Inorganic Vision Newsletter, we have discussed hydride analysis using FIAS coupled with AAS, in this issue we will look at some works with FIAS-ICPOES and continue hydride-ICPOES analysis.

Na and K analysis in cooking oil make easy with direct flame AAS
In accordance to EN14108 and EN14109, analysis of Na and K in cooking oil can be easily performed with AAS without tedious sample pre-treatment such as ashing or digestion. The oil is simply diluted between 10 to 25 times with a Xylene solution or kerosene. The Na/K content in the sample can be directly determined by a flame AAS at wavelength of 589nm and 766.5.

Milk analysis with ICPMS
The major and trace elements in milk powders can be analyzed using a simple sample preparation method, within one solution. This involves no digestion of the sample but an easy-to-follow and quick preparation of a slurry or suspension of the milk. The ICPMS parameters are optimized to allow extension of liner range for analysis of major elements (in % level) while maintaining good sensitivity for analysis of trace elements (in ppb level).

Stable Sample Introduction (SSI) dual spray chamber stretching the detection limit of ICPOES
Detection limit is commonly understood to be the smallest concentration we can measure with a particular technique. In fact, it is the point at which we can make a decision whether the element or compound is present or not. As such, to be able to improve instrument capability of differentiating a true signal from noise, one of achieving this is to reduce the signal noise. Read More...
