Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A sample preparation apparatus comprising:
a measurement unit configured to detect target particles contained in a first quantity of a sample acquired from a sample container;
a sample preparation unit configured to prepare a measurement sample from a second quantity of the sample;
a control unit configured to:
receive an identification of a type of particle detection reagent to be mixed with the second quantity of the sample;
using the received identification of the type of particle detection reagent, determine a target concentration of the target particles prescribed to properly measure a marker attached to the target particles;
operate the measurement unit to detect the target particles contained in the first quantity of the sample;
from the target particles in the first quantity of the sample detected by the measurement unit, determine a sample concentration of the target particles in the first quantity of the sample;
operate the sample preparation unit to adjust the second quantity of the sample, based on the determined sample concentration of the target particles in the first quantity of the sample, to have the target particles at the target concentration; and
operate the sample preparation unit to mix the type of particle detection reagent with the second quantity of the sample, adjusted to have the target particles at the target concentration, to prepare the measurement sample, wherein the measurement sample is used to detect the marker attached to the target particles.
