A low-temperature, high-power NMR probe head design is described which eliminates the problem of electric arc discharge commonly experienced during radiofrequency pulse cycling in a helium environment. A polychlorotrifluoroethylene (Kel-F) coil former, fitted with a solenoid coil, is heat-shrunk onto

3.1 Oil, referred to as polychlorotrifluoroethylene (pCTFE), is a polymeric mixture consisting primarily of trimers and tetramers of chlorotrifluoroethylene (CTFE) end-capped with chlorine. Inhalation studies have associated dose-related body weight loss, increased organ weights, and abnormal hepatic enzyme activities with

C8 polychlorotrifluoroethylene (pCTFE) oligomers accumulate preferentially in the liver during long-term oral exposure and appear to be more hepatotoxic than C6 oligomers. A repeated-dose gavage study was initiated to determine the relative contributions of the corresponding C6 (trimer) and C8
