how to increase the sampling rate and reduce the adc conversion time

aravindaguru:
hi,
I am trying to display the detected value of the sensors and it is displaying but the problem is ADC conversion is lagging to collect every value detected by the sensor is there any solution to solve this issue and to increase the sampling rate in Arduino zero

You need to post the code you are using so that we may read it and look for ways to improve it.
without seeing the code anyone would be providing an answer deprived of important information.
