Abstract
A method may include maintaining a sample comprising an ionic species and an optical indicator at an elevated temperature above 25° C. on a semi-conductive microfluidic die during an incubation period, intermittently interrogating the sample with an interrogating light during the incubation period and sensing a response of the sample to the interrogating light, wherein the sample is interrogated with the interrogating light only during those times at which the sample is being sensed.
Claims15
A method comprising:
- maintaining a sample comprising an ionic species and an optical indicator at an elevated temperature above 25° C. on a semi-conductive microfluidic die during an incubation period;
- intermittently interrogating the sample with an interrogating light during the incubation period, wherein the intermittent interrogation of the sample with the interrogating light has a varying frequency during the incubation period;
- and
- sensing a response of the sample to the interrogating light, wherein the sample is interrogated with the interrogating light only during those times at which the sample is being sensed.
A method comprising:
- maintaining a sample comprising an ionic species and an optical indicator at an elevated temperature above 25° C. on a semi-conductive microfluidic die during an incubation period;
- intermittently interrogating the sample with an interrogating light during the incubation period by pulsing the interrogating light a plurality of times during the incubation period, wherein each pulse of the plurality of pulses includes turning the interrogating light on and off during the incubation period, wherein the intermittent interrogating of the sample has a duty cycle of less than 40%, and wherein the intermittent interrogating the sample with the interrogating light includes using a varying frequency during the incubation period;
- and
- sensing a response of the sample to the interrogating light during those times at which the sample is being interrogated with the interrogating light.
