An infrared light source device includes: a heater portion which emits infrared light by being heated; and a cover member arranged to cover an entire circumference of the heater portion without contacting the heater portion, and having a hole formed therein for emitting the infrared light from the heater portion to outside. A material for the cover member is a pure aluminum (an aluminum alloy with a purity of 99% or more), which has a high heat reflectivity and is less likely to be denatured by heat dissipation from the heater portion.

Embodiments of this invention relate generally to a miniature multi-spectral system to detection pathogen, biomarkers, or any compound from a sample. In one example, a miniature multi-spectral system comprises a first miniature spectrometer to generate a first spectral output based on a sample, a second miniature spectrometer to generate a second spectral output based on the sample, and a processor coupled to the first and the second miniature spectrometers. The processor is configured to execute instructions to perform data fusion of the first and second spectral outputs to generate fused data, and to apply artificial intelligence (AI) of an AI module to the fused data to identify a pathogen, biomarker, or any compound from the sample.

A system includes a dip tube, a feed line, and a check valve. The dip tube is inserted through an opening in a source of chemical precursor and into the chemical precursor in the source. A portion of the feed line is located in the dip tube. The feed line passes out of the dip tube. The chemical precursor is capable of flowing out of the source through the feed line in a downstream direction. The check valve is located in the portion of the feed line in the dip tube. The check valve permits the chemical precursor to pass substantially only in the downstream direction. The feed line is coupled to a transfer pump that draws the chemical precursor out of the source through the portion of the feed line in the dip tube.

Systems and methods are provided for gathering and segregation of oil extracted from a resource fields with a plurality of disparate sources in relatively close proximity. Instead of assigning a quality and/or destination for crude oil from an extraction source based on the origin of the crude oil, the crude oil can be characterized while still in local storage at or near the wellhead prior to transport to a refinery, a shipping or pipeline terminal, or another type destination for crude oil. Based on the characterization, one or more characteristics of the crude oil can be used to assign the crude oil to one of a plurality of destinations. The crude oil can then be transported to the assigned destination.

The invention pertains to a device for determination of a catalyst state in a chemical reactor and to a method for detecting a catalyst state under in situ reaction conditions. A reactor is provided with a solid catalyst provided in a reactor chamber. A fluid sample is taken from the reactor chamber and is transferred to a sample chamber. The temperature at the extraction site of the sample in the reactor chamber is determined and the temperature of the sample chamber is adjusted to the same temperature. A small amount of the catalyst provided in reactor chamber is provided in sample chamber and is contacted with the sample flow. Spectroscopic information is then obtained on the catalyst provided in sample cell, e.g. by an IR spectrometer.

The present disclosure includes discloses a method for analyzing a multi-component gas sample using spectroscopy in combination with the measurement of extrinsic or intrinsic properties of the gas sample. The results of the spectroscopic analysis and the measurement are combined to quantify a gas component unseen by the spectroscopic analysis.
