The high-pressure discharge lamp comprises a sealed lamp vessel having a quartz glass wall enclosing a discharge space. The frequency sampling phase detector of the present invention may include a phase detector coupled with sample and hold circuitry. The method further includes determining if the artifact suppression factor falls within a range. By measuring an electrical parameter in the circuit, the pump leak monitor is capable of measuring the conductivity of the fluid in the pump housing. The organic electronic device has a conductive path including fine particles, a first organic semiconductor molecule which has a first conductive type and binds at least two of the fine particles together, and a second organic semiconductor molecule which has a second conductive type and is captured in a state of noncovalent bond in a molecule recognition site that exists among the fine particles.
