Appendix A: Hydrofluoric acid (HF) Applications
Hydrouoric Acid (HF) is a highly corrosive inorganic acid; therefore, it must be handled with extreme caution. The
BLADE instrument requires the use of TFM liners purchased from CEM Corporation or its authorized dealer and
“QVL” must be selected as the vessel type when using HF.
Only those trained in the use of HF should be allowed to use the instrument when using HF.
Contact CEM Corporation for non-hydrouoric acid use of the TFM liner.

WARNING
Proper precautions must be taken to avoid contact with acid or acid vapors. Personal
protective equipment (PPE) should be worn as outlined in the user’s safety program for
hazardous materials and the manufacturer’s safety data sheet. Refer to these guidelines for
proper handling and disposal.
