A method is provided which is capable of efficiently taking most of a precious sample into an extraction vessel without wasting when the sample is extracted from a collection section of a sampling rod. The method includes the steps of collecting a sample using a sampling rod formed of a rod body and a collection section attached to the rod body, inserting the sampling rod into the extraction vessel, placing the rod body in a gap formed in a grappling hook section which is disposed in an insertion path of the sampling rod, the gap having a width smaller than a diameter of the collection section and being capable of receiving the rod body, withdrawing the rod body with the rod body being placed in the gap and detaching the collection section from the rod body by hooking the collection section to the grappling hook section.

A glow starter comprises a discharge vessel, filled with a filling including a rare gas, substantially transmitting ultraviolet rays of about 300 nm or less. A pair of electrodes, which are arranged in the discharge vessel, is adapted and arranged to touch each other by being heated by a glow discharge. The glow starter may be used for a high pressure discharge lamp, a high pressure discharge lamp apparatus, or a lighting fixture.

An electrodeless high intensity discharge lamp has a light transmissive ceramic arc tube for containing a discharge sustaining medium and a hollow tube member. An excitation coil for causing an arc discharge is situated about the arc tube. The ceramic arc tube includes a first portion for developing the arc discharge therein and a second portion protruding outwardly from the first portion. The hollow tube member is so disposed in the second portion that a space is provided between the inner wall surface of the second portion and the outer wall surface of the hollow tube member. The space is in communication with the interior of the first portion for allowing the medium to be condensed and retained during the lamp operation.
