As a means of exciting noble gases at atmospheric pressures, Lovelock developed a spark device of high sensitivity, capable of detecting as little as 10^{minus 13} mole of most organic materials. The detector consisted of a spark gap made of platinum wire sealed in a glass tube. The voltage across the 5-10 mm spark gap is measured with an electrostatic voltmeter. With pure argon subjected to an applied voltage of 2000 V to create sparks, the breakdown potential measured was logarithmically related to the concentration of vapor added to the argon.  2, record 1, English, - gas%20discharge%20detector
