Light ones are more easily deflected than heavy ones, so the two forms of carbon get separated, and when each atom reaches a detector at its expected arrival spot, it can be counted.

轻的原子较重的更容易转弯，从而能分离两种碳原子，每个碳原子到达预定的监测点，计数器就会计数。

Dr Krausz did it by recording the arrival times of different electrons using a piece of equipment called a multi-channel plate detector.
