Detail:
Platinum Long Life Shield Plate
In the context of Inductively Coupled Plasma (ICP) analysis, a “long life shield plate” refers to a specialized component within the ICP torch system, usually made of platinum, designed to protect the surrounding components from the intense heat of the plasma while providing a long lifespan compared to standard shield plates, allowing for extended use in demanding analytical applications; it’s often part of a “Shield Torch System” that helps maintain stable plasma conditions and achieve optimal sensitivity in ICP-MS analysis.
Key points about long-life shield plates:
- Function: They act as a heat barrier. In doing so, they prevent the plasma from directly contacting and damaging other parts of the torch.
- Material: Platinum is the material of preference due to its high resistance to heat and corrosion.
- Benefits: Extended lifespan, Improved stability of the plasma
- Cool Plasma Mode: Enables the cool plasma mode, which is essential for achieving the lowest backgrounds necessary for ultra-trace determination of elements like potassium (K), calcium (Ca), and iron (Fe).
