文摘
- •
A tungsten coil trap was firstly employed to ICP-MS for Cd analysis in food.
- •
The modified gas circuit showed an effective performance for plasma stability.
- •
The minimum sample mass of fresh food samples well ground proved < 30 mg.
- •
This SS-ETV-ICP-MS method is fast, accurate, easy, green and safe.
