Methods and systems for digital measurements are provided. In an embodiment, the method includes producing a plurality of droplets, wherein at least one of the droplets of the plurality of droplets contains an analyte molecule from a sample; measuring at least a first portion of the plurality of droplets to determine individual volumes of droplets in the first portion of the plurality of droplets; analyzing at least a second portion of the plurality of droplets to determine a number of droplets in the second portion of the plurality of droplets that contain the analyte molecule; and using individual volumes of the droplets in the first portion of the plurality of droplets and the number of droplets in the second portion of the plurality of droplets that contain the analyte molecule to determine the concentration of the analyte molecule in the sample.

Methods and systems for performing digital measurements

Methods, devices and systems for performing digital measurements are provided.

A process for a pre-concentration unit including: a sorbent material coated passage-way having an entrance for receiving a hydrocarbon-containing groundwater sample and for pre-concentrating the hydrocarbons in a hydrocarbon-containing groundwater sample by successive sorption/desorption cycles, and having an exit for discharging the pre-concentrated hydrocarbons; a heating unit for heating the sorbent material coated passage-way; and; an array of shear horizontal-surface acoustic wave sensors with coatings adapted for detecting and quantifying the pre-concentrated hydrocarbons, disposed at the exit of the sorbent material coated passage-way; and a housing for enclosing the pre-concentration unit and the array of shear horizontal-surface acoustic wave sensors, adapted for continuous use at a body of hydrocarbon-containing groundwater, and coupled to mathematical methods for generating concentrations of specific analytes from both transient and steady-state signals.

Detection of hydrocarbons in aqueous environments

A method and system for performing biochemical detection or analysis on micro- and nano-scale subcellular component within a single biological cell is provided. An integrated platform device and method to perform the biochemical analysis is also provided.
