Abstract: System for quantifying a composition of a target sample based on a scan output of a first type of sensor includes a reference database, a custom database and a set of modules. The set of modules includes an analytical model creation module that creates an analytical model of the first type of sensor, a sample processing module that processes samples that include accurately known compositions using the first type of sensor under a standard pressure condition, a molecular fraction estimation module that estimates molecular fraction of the samples using an estimation method and the analytical model, an analytical model optimization module that optimizes the analytical model by comparing the molecular fraction of the samples with a pre-determined molecular fraction of the samples, and a target composition estimation module that estimates a composition of the target sample based on the scan output using the estimation method with the optimized analytical model.

Abstract: A system includes a first type of sensor and an estimation system that is connected to first type of sensor. The estimation system is configured to (a) identify a best peak shape for estimation of known gas mixtures by analyzing characterization data across known gas mixtures, with added noise, using machine learning, (b) generate a plurality of actual peak shapes, in first type of sensor, for several different instances using standard gas mixtures to provide an actual peak shape among the plurality of peak shapes as calibrating input to calibrate first type of sensor and (c) calibrate first type of sensor by automatically adjusting parameters of first type of sensor for optimizing actual peak shape to match with desired peak shape.

Abstract: A system for scanning a gas mixture using a sensor is disclosed. The system includes a matrix multiplication module configured to pre-multiply a B matrix with a diagonal matrix that is created with a vector of nominal concentration of the set of gases to obtain an adjusted B matrix (Ba) and a mass to charge ratio extraction module that is configured to select a set of mass to charge ratios for the set of gases to scan in a time budget based on the adjusted B matrix (Ba). The B matrix is a multiplication of P, T, C and R matrices, wherein P is a convolution matrix representing peak shapes, T is transmission efficiencies at each integral mass to charge ratio, R is relative ionization potentials for each gas and C is a reference spectrum representing idealized responses for each gas at the integral mass to charge ratio.
