Claim 0:
1. A microparticle measuring apparatus, comprising:
a liquid sample reservoir connected to a liquid sample flow channel, wherein the liquid sample reservoir is configured to store a liquid sample including microparticles;
a liquid sheath reservoir connected to a liquid sheath flow channel, wherein the liquid sample flow channel and the liquid sheath flow channel are connected to a flow channel;
a sorted liquid reservoir connected to a sorting flow channel;
a waste liquid reservoir connected to a discarding flow channel, wherein the sorting flow channel and the discarding flow channel are connected to the flow channel;
a plurality of light detectors configured to detect, at different positions, optical information emitted from the microparticles that flow through the flow channel, wherein the plurality of light detectors includes:
a first light detector that includes a first plurality of channels, and
a second light detector that includes a second plurality of channels,
the first light detector including the first plurality of channels is at a first position on the flow channel, and
the second light detector including the second plurality of channels is at a second position on the flow channel different from the first position; and
circuitry configured to:
control a detection timing of each light detector of the plurality of light detectors based on:
a trigger signal detected at a first reference channel of the first plurality of channels of the first light detector, and
an optical signal detected at a second reference channel of the second plurality of channels of the second light detector;
set a light detection process period of the first reference channel of the first plurality of channels of the first light detector based on a time period in which the trigger signal detected at the first reference channel exceeds a threshold value;
add a first time period and a second time period to the set light detection process period, wherein
the first time period is added prior to the set light detection process period, and
the second time period is added subsequent to the set light detection process period; and
control a detection process period of the second light detector based on the set light detection process period of the first reference channel that includes the first time period and the second time period.
