Overview[ edit ] Parts-per notation is often used describing dilute solutions in chemistryfor instance, the relative abundance of dissolved minerals or pollutants in water. When working with aqueous solutions, it is common to assume that the density of water is 1.

Therefore, it is common to equate 1 kilogram of water with 1 L of water.

Similarly, parts-per notation is used also in physics and engineering to express the value of various proportional phenomena. For instance, a special metal alloy might expand 1. In nuclear magnetic resonance NMR spectroscopy[ edit ] In nuclear magnetic resonance spectroscopy NMRchemical shift is usually expressed in ppm.

It represents the difference of a measured frequency in parts per million from the reference frequency. The reference frequency depends on the instrument's magnetic field and the element being measured.

It is usually expressed in MHz. Parts-per notation gives a dimensionless quantity that does not depend on the instrument's field strength. This is equivalent to about fifteen minutes out of one day.


One part per thousand should generally be spelled out in full and not as "ppt" which is usually understood to represent "parts per trillion". Note however, that specific disciplines such as oceanography, as well as educational exercises, do use the "ppt" abbreviation.

This is equivalent to about one and a half minutes out of one day. This is equivalent to about nine seconds out of one day. In contrast, in financethe basis point is typically used to denote changes in or differences between percentage interest rates although it can also be used in other cases where it is desirable to express quantities in hundredths of a percent.

For instance, a change in an interest rate from 5. As with interest rates, the words "per annum" or "per year" are often omitted. This is equivalent to about three seconds out of a century. This is equivalent to about thirty seconds out of every million years.

This is equivalent to about two and a half minutes out of the age of the Earth 4. Although relatively uncommon in analytical chemistry, measurements at the ppq level are sometimes performed.

The main problems with the parts-per notation are the following: Unless the meaning of "ppt" is defined explicitly, it has to be determined from the context. For example, the conversion factor between a mass fraction of 1 ppb and a mole fraction of 1 ppb is about 4.

For volume fraction, the suffix "V" or "v" is sometimes appended to the parts-per notation e. To distinguish the mass fraction from volume fraction or mole fraction, the letter w standing for weight is sometimes added to the abbreviation e.

This, in turn, leads them to not specify their usage in their publications, and others may therefore misinterpret their results. Many academic papers of otherwise excellent level fail to specify their usage of the parts-per notation.

SI-compliant expressions[ edit ] SI-compliant units that can be used as alternatives are shown in the chart below.In science and engineering, the parts-per notation is a set of pseudo-units to describe small values of miscellaneous dimensionless quantities, e.g.

mole fraction or mass these fractions are quantity-per-quantity measures, they are pure numbers with no associated units of mtb15.comly used are ppm (parts-per-million, 10 −6), ppb (parts-per-billion, 10 −9), ppt . Watch video · In this video, Judy emphasizes the importance of the presentation and the correct formatting of a technical report.

Learn how using the correct margins and line justification, font size and style, levels of headings, numbering, and binding are all part of producing an effective technical report.

Responsible for anticipating, assessing and controlling risks posed by the handling and use of bacteria, viruses, potentially infectious human materials and other microorganisms, toxins and biological materials, in research and clinical practice. A presentation report is designed to offer details about a subject and is given to a person or group of people in the form of a presentation.

Presentations often include visuals, such as charts or slide shows, although they are not required for every type of presentation. Faculty Name. Department. Email ; Armstrong, Piers.
