LAGM™

Laser Ablation-GED- MSAG system

•  
• Direct Analysis without Cutting Wafers
• The conventional LA-ICP-MS system needs to use a small enclosed cell in which a small solid sample is placed.
• LAGM doesn’t require the small enclosed cell. A solid sample is laser ablated under particle free environment, and generated particles are aspirated together with clean air by an ejector, which are introduced to the plasma of ICP-MS via GED (Gas Exchange Device).
• Superior Quantitation Capability
• Another issue of the conventional LA-ICP-MS is the quantitation. Solid standard reference materials (SRMs) are commonly used, but the particle amount generated from a solid sample and the SRMs would be different, which makes difficult to perform accurate quantitation.
• LAGM uses the MSAG_DS that injects a few μL/min of mixed standard solution that are vaporized and introduced to the plasma of ICP-MS almost 100%. As a result, the method of standard addition or internal standard can be used while laser ablating a solid sample, which allows accurate quantitation.
