1. A high-temperature condensation particle counter (HT-CPC), comprising:
a saturator block configured to accept directly a sampled particle-laden gas flow;
a condenser block located downstream and in fluid communication with the saturator block;
an optics block located downstream and in fluid communication with the condenser block; and
a makeup-flow block located in fluid communication with and between the condenser block and the optics block, the makeup-flow block being configured to reduce volatile contents from re-nucleating in the optics block and reduce particle losses within the optics block.
