(Avoid using rare earths in fluoride matrices.)\u003c\/li\u003e\n\u003cli\u003eAre there any possible spectral interferences upon the IS line?\u003c\/li\u003e\n\u003cli\u003eIs the concentration of the IS sufficient to give a good signal to noise ratio?\u003c\/li\u003e\n\u003cli\u003eCan your sample possibly contain the IS element as a natural component?\u003c\/li\u003e\n\u003cli\u003eIs the IS clean? Are the trace impurities reported on the certificate of analysis?\u003c\/li\u003e\n\u003cli\u003eIs your method of addition of the IS very precise? Is the same amount added precisely to all standards, blanks, and samples?\u003c\/li\u003e\n\u003cli\u003eDo you always use the same lot of IS for the standards and samples? (Using the same lot is very important.)\u003c\/li\u003e\n\u003cli\u003eIf your plasma temperature were to go up or down, is the IS likely to follow the same pattern of intensity change as the analyte? This is where many IS problems occur (i.e., - an IS with the same plasma \/ temperature behavior as the analyte is difficult [at best] to find for each analyte while avoiding other issues listed above).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cbr\u003e\n\u003c\/div\u003e\n\u003c!---------------IMPORTANT-ADD THIS SECTION TO THE END OF THE HTML-------------\u003e\n\u003cscript\u003e\/\/ \u003c![CDATA[\nvar acc = document.getElementsByClassName(\"accordion\");\nvar i;\n\nfor (i = 0;
