Smile AgNi or AgSnO+InO in ICP(inductively coupled plasma) help

Dear all friends:

Need help~~~~

I am doing ICP(inductively coupled plasma) experiment, my sample there are 2 kinds of silver wire,
2.AgSnO + InO.

Both 2 kinds wire are heated with Nitrate Acid(HNO3, concentration 70%) and then dissolved into together.
After mix with HNO3 and dissolved, produce little precipitate(solid).

This is the problem here. I do not want to see any precipitate.

follows I tried and fail
1.AgNi + HNO3 will produce precipitation.
2.AgSnO + InO + HNO3 after them dissolved, have little white precipitation more than 1.

Any one support good idea, let them dissolved completely and in liquid status with no precipitate?
DO I have any work to prepare?

The best regards by Emily
thanks for read!
