A spectral analysis apparatus includes a light transmissive envelope, a first and second electrode, a sleeve, and a first and second electrical contact. The light transmissive envelope includes a first end portion and a second end portion and the envelope contains a fluid operable to emit light when electrically energized. The first electrode is disposed upon an external surface of the first end portion and is completely external to the envelope. The second electrode is disposed upon an external surface of the second end portion and is completely external to the envelope. The sleeve defines a cavity configured to removably receive the envelope. The first electrical contact is in communication with the cavity and is configured to electrically connect to the first electrode when the envelope is within the sleeve. The second electrical contact is in communication with the cavity and is configured to electrically connect to the second electrode when the envelope is within the sleeve. The first and second electrical contacts are connectable to an electrical power supply, and the electrodes electrically energize the fluid when electrically connected to the electrical power supply.
