Abstract

A photometer (30) and a test sample holder (50), with the holder having a light-blocking, black upper section (52, 54) and a light-transparent, lower section test sample vial (56), for use with the photometer (30). The photometer (30) includes an O-ring seal (75) at an input (40), to the light measurement sample chamber (100), so on insertion of the holder (50), with a test sample (53) to be detected in the test vial (56), the upper section (52, 56) blocks interfering light from the chamber (100).

Claims

AMENDED CLAIMS
[received by the International Bureau on 18 August 1998 (18.08.98); original claims 16 and 20 amended; remaining claims unchanged (1 page)]
Claim 15. The method of claim 11 which includes employing a test sample holder having an upper section of a longitudinal, movable cap, with a swab, to collect a test sample and a hollow, tubular, middle section, the upper section of the cap and middle section composed of a black, light-blocking plastic.
Claim 16. The method of claim 11 which includes removing the inserted test sample holder, to permit the light-blocking cap to move to a light-blocking position at the inlet to the sample chamber.
Claim 17. A photometer adapted for use with a test sample holder to measure luminescence from a test sample, which comprises a photometer having a sample-holding chamber adapted to receive therein, a transparent test vial of a test sample holder with a test sample to be measured, the test sample holder having an upper light-blocking section and a peripheral surface, and having an entrance port and sample-holding chamber with an inlet, and optical-electrical means to define an optical light path, and to measure the luminescence of the test sample in the light path in the sample-holding chamber, and which photometer includes an engaging means dimensioned to engage and seal against the exterior surface, light-blocking surface of the test sample holder, to block external light from said chamber.
Claim 18. The photometer of claim 17 wherein the engaging means comprises an elastomeric O-ring seal.
Claim 19. The photometer of claim 17 wherein the engaging means is positioned at the inlet to the sample- holding chamber.
Claim 20. The photometer of claim 17 which includes biased blocking means to block the inlet of the sample- holding chamber when the test sample holder is not inserted and to permit the entry of the test vial into the optical light path, on insertion of the test sample holder into the entrance port.
