WebFeb 27, 2024 · Both ppm (parts per million) and molarity are measures of concentration. Did you know that ppm is used in different ways depending on the context? When dealing with dilute solutions, 1 ppm can be approximated as 1 mg 1\ \text{mg} 1 mg of substance per liter of water, or 1 mg / L 1\ \text{mg}/\text{L} 1 mg / L.. On the other hand, molarity is … WebLEL sensors measure percent of LEL. For example, Gasoline has an LEL of 1.4%. Therefore, 100% of LEL is 14,000 ppm of gasoline, 10% of LEL is 1,400 ppm of gasoline and 1% of LEL is 140 ppm of gasoline. 140 ppm of gasoline is the lowest amount of vapor that the LEL monitor can "see." WebA long-path gas cell with a light path of 10 m or 20 m is used to measure ppm-order or lower concentration gas samples. These gas cells do not offer a 10 m light path in a straight line. Rather, they comprise three mirrors, as shown in Fig. 4, and the long light path is achieved by repeated reflections within the gas cell 2). steinhardt grad application
