Heavy Metals Analysis of Countertop Water Filter Cartridges

I need a laboratory to perform quantitative heavy metals testing on countertop water filter cartridges, one of which is a fluoride-type, and the other is a charcoal filter. Primary target analytes are thallium, lead, and antimony, with possible additional analysis for barium, cesium, and aluminum, depending on laboratory capability and pricing. Testing may include leachate analysis or other recommended methods for evaluating potential metal release from filter media containing activated alumina and coconut hull charcoal. Please provide available test methods, detection limits, sample requirements, turnaround time, and pricing for one or both filter types.
