We are currently looking to source AAS units specifically designed for precious metals analysis, including gold and silver. The effectiveness and precision of these systems are crucial for our operations, so we would appreciate detailed info on the available models, their features, and pricing. Furthermore, if you could provide insights on lead times, any warranties, and after-sales support, that would be helpful. We aim to establish a long-term relationship with reliable suppliers, so any additional recommendations on complementary products would also be great. Thanks!
