Hi All
Will a matrix of 2%HNO3 and 0.5%HCL be OK for stability of Ag to prepare 0-300ppb calibration curve or should the HCL rather be 1%?

I've used 0.5% up to low ppm levels for Ag and there was enough excess Cl to stabilize it. If you noticed poor recovery with 0.5% that would be your indicator to increase to 1% but I doubt it will be needed.
