Glass Expansion AT5004: Long Life Platinum Shield Plate for Agilent ICP-MS
The Glass Expansion AT5004 is a premium Long Life Platinum Shield Plate designed to enhance the performance and durability of Agilent 7500, 7700, 7800, 7900, 8800, and 8900 series ICP-MS instruments. This essential component plays a crucial role in protecting the ICP torch and interface components from the intense heat of the plasma, while also contributing to plasma stability and ion energy control.
Crafted from high-purity platinum by Glass Expansion, a world-renowned manufacturer of ICP-MS consumables, the AT5004 shield plate offers superior resistance to heat and corrosion compared to standard shield plates. This extended lifespan reduces instrument downtime and maintenance costs, making it a valuable upgrade for any laboratory running these Agilent ICP-MS systems.
Key Features & Benefits
- Extended Component Lifespan: Made from high-purity platinum for maximum resistance to plasma heat and corrosive matrices, significantly outlasting standard shield plates.
- Improved Plasma Stability: Helps maintain a stable and consistent plasma, leading to more reliable and reproducible analytical results.
- Enhanced Sensitivity: Contributes to better ion energy control and can reduce capacitive coupling, potentially improving sensitivity and lowering background signals.
- Cool Plasma Mode Compatibility: Enables and supports "cool plasma" conditions, which are essential for achieving the lowest detection limits for elements like K, Ca, and Fe.
- Reduced Maintenance: Longer lifespan means fewer replacements and less frequent instrument maintenance.
- Direct OEM Replacement: Designed as a direct, high-quality alternative to Agilent part number G1833-65419.
