This list has potassium (K) on it twice. Is the second K suppose to be P for phosphorus?

No, that is a typo resulting from inconsistently arranging the list alphabetically by element name and symbol. Lead (Pb) was listed twice as well. The list has been corrected now.

ICP standard QCS-27 has been replaced by cat number QCS-27-100, I used to also order standard cat number ICQ100-27 and I need to know if this standard has been discontinued?

Our product ICQ100-27 remains the same as it has been. It is still available.

I need ICQ100-7 with Ag at 50ppm, the other six analytes as they are. Is this possible?

Yes, this should be possible. Please contact your sales representative to submit a custom standard request. They will be able to give you pricing and the necessary lead time of the standard.
