PPM-Parts Per Million: Number of grams of solute per 1 million grams of solution. ppm=[mass of solute/mass of solution]*10 to the 6th power
&
PPB-Parts Per Billion: Number of grams of solute per 1 billion grams of solution.
ppb=[mass of solute/mass of solution]*10 to the 9th power.

BlakePPM (parts per million) and PPB (parts per billion) are both used as units of concentration to measure the amount of a substance in a mixture. The main difference between the two is the scale of measurement – PPM indicates one part of a substance per one million parts of a solution, whereas PPB indicates one part of a substance per one billion parts of a solution. This means that PPB is a thousand times smaller than PPM.

How can you prepare 1ppb from1000ppm sodium standard?
To prepare a 1 ppb sodium solution from a 1000 ppm sodium standard, you can dilute 1 mL of the 1000 ppm sodium standard with 999 mL (or 999 g) of solvent. This will result in a final solution with a concentration of 1 ppb, as 1 mL is equivalent to 1 mg in this case.
What is ppm by volume?
Parts per million (ppm) by volume is a unit of measurement used to express the concentration of a substance in a gas as a ratio of the volume of the substance to the total volume of the gas. It is calculated as the volume of the substance divided by the total volume of the mixture multiplied by one million.
What is ppm-ppb-ppt used to express?
PPM (parts per million), PPB (parts per billion), and PPT (parts per trillion) are used to express concentrations of substances in a mixture or solution. They are used to indicate the proportion of one substance in relation to the total amount of substances present, with PPM being the largest and PPT being the smallest unit of measurement.
What is the proper ppm of the sanitizer?
The proper ppm (parts per million) of sanitizer can vary depending on the specific sanitizer being used and the surface or item being sanitized. It is important to follow the manufacturer's instructions and guidelines for the correct ppm concentration to ensure effective sanitization. Typically, the range for sanitizer ppm in food establishments is between 50-200 ppm.
What is the difference between mcg and ppm?
Mcg (microgram) is a measurement of weight or mass equal to one millionth of a gram, while ppm (parts per million) is a measurement of concentration expressing the amount of one substance in relation to a million units of a whole. In other words, mcg specifies the weight of a substance, while ppm indicates how much of a substance is present in a larger quantity.
