Answer:
electron capture detectors (ECD)
Explanation:
Electron capture detectors (ECD) would be most sensitive for GC analysis of PCBs.
Zero degree celcius = 273.15 degree kelvin
Simply, to get the value of 45.1 degree celcius in kelvin, we will add 273.15 to the given value (45.1).
Degree in kelvin = 45.1 + 273.15 = 318.25 degree kelvin
Approximating to the nearest tenth, the value will be 318.3 degree kelvin
