Embodiment 1

[0037] Example 1. A method for authenticating a working fluid comprising a UV-reactive chemical marker, the method comprising: (a) exposing at least a portion of the working fluid to light having a wavelength in the range of about 10-400 nm , thereby causing the chemical marker to generate a signal; (b) detecting the signal via a sensor system; and (c) comparing the signal to a reference signal associated with an actual working fluid.

Embodiment 2

[0038] Embodiment 2. The method of embodiment 1, further comprising generating an output indicating whether the working fluid is the authentic working fluid.

Embodiment 3

[0039] Embodiment 3. A method for in-situ verification of a working fluid comprising a UV-reactive chemical marker, the method comprising: (a) introducing the working fluid into a mechanical system; (b) introducing the working fluid Exposure of at least a portion of said chemical marker to light having a wavelength in the range of about 10-400 nm, thereby causing said chemical marker to generate a signal; (c) detecting said chemical marker via a sensor system disposed on or within said mechanical system a signal; and (d) comparing said signal generated by said chemical marker to a reference signal associated with an actual working fluid.

Abstract

Systems and methods are provided for authenticating working fluids. The systems and methods include exposing at least a portion of a working fluid containing a UV-reactive chemical marker to light having wavelengths in the range of about 10-400 nm, thereby causing the chemical marker to generate a signal. The signal can be detected via a sensor system and compared to a reference signal that is associated with an authentic working fluid. An output may be generated to indicate whether the working fluid is the authentic working fluid.

Description

technical field [0001] The present invention relates to systems and methods for validating useful working fluids, such as lubricants, oils, coolants, hydraulic fluids, fuels, and oilfield chemicals, in various equipment and mechanical systems. Background technique [0002] Working fluids are important components of various mechanical systems (eg, engines). They aid in functions such as lubricating moving parts, transmitting force or energy on mechanical systems, protecting components from wear, cleaning, protecting electrical components, or even a combination of these functions. These fluids may generally contain hydrocarbon-based oils formulated with one or more performance additives selected to enhance one or more performance characteristics. [0003] Unfortunately, counterfeiting of authentic working fluids is a significant problem for working fluid manufacturers. Counterfeit working fluids may be of lower quality than genuine products and may have inferior properties t...
