Method and apparatus for analyzing intra-cell delay times. An area of the auxiliary heating element layer is smaller than that of the main heating element layer, and while the substrate and the object to be heated are heated with heat generated from the main heating element layer, heat escaping from the substrate is supplemented with heat generated from the auxiliary heating element layer. The mapping protocol can be configured to convert packets including the flow ID into packets that conform with a given addressing protocol for routing to the application server. The oil carrier and the sample droplets flow through the inlet port with an equivalent fluid flow subtracted through the compensating port.
