A sample handling device for handling a fluid sample in an analyzer for analyzing the fluid sample includes a sample needle having a lumen (197) through which the fluid sample can be passed, and a movement apparatus for moving the sample needle. The sample needle is rotatably mounted with respect to the movement apparatus.

An injector includes an injection device and a round turret provided on a front side of the injection device. A sampler is provided with a vial holder and a conveyance arm. The injector has an accessible structure in which a moving path of the conveyance arm of one sampler arranged on the side of the two injectors for accessing the round turret of each of the two injectors is secured regardless of the size of the round turret, when two injectors are arranged so that the back sides of the injection devices face to each other.

A sampling needle (21) is inserted into a sample container (12) by a needle-driving mechanism (23) to collect a sample liquid from the sample container. A depth information acquirer (52) acquires insertion depth information, i.e., a piece of information concerning an insertion depth of the sampling needle into the sample container. A needle-rinsing length setter (54) sets a needle-rinsing length which is an insertion length of the sampling needle into a rinse storage tank (30) having an open top, based on the insertion depth information. A controller (51) controls the needle-driving mechanism so that a portion of the sampling needle extending from the tip of the sampling needle over the needle-rinsing length is inserted into the rinse storage tank. The needle-rinsing length setter is configured to set a shorter needle-rinsing length for a smaller insertion depth of the sampling needle into the sample container, to shorten the needle-cleaning time.

A ferrule includes a deformable portion and a rigid sleeve surrounding at least a portion of the deformable portion. The deformable portion includes between about 5% and about 50% graphite. The deformable portion further includes between about 50% and about 95% polyimide. The rigid sleeve can include a metal, such as stainless steel.

A sample vaporization chamber for gas chromatograph includes a cylindrical insert provided, at least on a lower end side of an inner peripheral surface or an outer peripheral surface thereof, with a first threaded portion, and an insert fixing portion provided with a second threaded portion to be threaded with the first threaded portion in the inner space of the housing. The insert fixing portion is configured to fix the insert in the inner space of the housing in a state in which the insert is accommodated in the inner space by threading the first threaded portion of the insert inserted in the inner space through the opening with the second threaded portion.
