To help compare different orders of magnitude, the following lists describe various mass levels between 10−40 kg and 1053 kg.
The table below is based on the kilogram (kg), the base unit of mass in the International System of Units (SI). The kilogram is the only standard unit to include an SI prefix (kilo-) as part of its name. The gram (10−3 kg) is an SI derived unit of mass. However, the names of all SI mass units are based on gram, rather than on kilogram; thus 103 kg is a megagram (106 g), not a "kilokilogram".
The tonne (t) is a SI-compatible unit of mass equal to a megagram, or 103 kg. The unit is in common use for masses above about 103 kg and is often used with SI prefixes.
Other units of mass are also in use. Historical units include the stone, the pound, the carat, and the grain.
For subatomic particles, physicists use the mass equivalent to the energy represented by an electronvolt (eV). At the atomic level, chemists use the mass of one-twelfth of a carbon-12 atom (the dalton). Astronomers use the mass of the sun (M☉).
This file shows 190 femtograms/drop of CMPO and Lanthanide chelates thereof, being shot via IBF into Bruker Micro ToF, MS. If you want to see a system 25 times faster you have to ask Drew Sauter. This MS technique use induction based fluidics (IBF) which is the most input efficient (i.e., 100%)and fastest mass spectrometry sample input technique in the world ! Attograms are just around the corner. Visit nanoliterdotcom!
Heather Holeman, Ph.D., Head of Life Science Reagents and Kits, MilliporeSigma, introduces the SMCxPRO™, a new high sensitivity protein quantifier, at ACCR 2017. Dr. Holeman explains how single molecule counting technology allows researchers to detect biomarkers with femtogram sensitivity. Dr. Holeman also discusses the applications of the instrument in cancer research, including biomarker discovery, assay development and drug discovery.

He received his B.S. degree from Univ of Science and Technology of China. ABSTRACT Nanowires and nanocrystals represent important nanomaterials with one-dimensional and zero-dimensional morphology, respectively. Here I will give an overview on the research about how these nanomaterials impact the critical applications in faster transistors, smaller nonvolatile memory devices, efficient...
Single molecule array (Simoa™) testing is a powerful new technique that is orders of magnitude more sensitive than standard sandwich based immunoassay techniques. Traditional ELISA measurements are limited to pg/ml levels of detection. The RayBio Ultrasensitive Simoa Testing Services reach femtogram (fg/ml) levels, allowing the detection and quantification of biomarkers at concentrations previously difficult or impossible to measure.
Fifth video in a series of videos discussing concentration calculations commonly used in a laboratory. More specifically a molecular biology lab. This particular video shows the basics behind setting up and calculating a serial dilution. This procedure can be used to establish a standard curve from a solution of known concentration.

This presentation, given by Dr. John Ludlow, Executive Director of Regenerative Medicine, Zen Bio Inc, at AACR 2017, explores methods for utilizing extracellular vesicles such as exosomes and microvesicles. Dr. Ludlow begins by introducing extracellular vesicles and discussing their potential as biomarkers and therapeutics. Dr. Ludlow then goes on to detail how the MACSPlex Exosome Kit from Miltenyi Biotec can be used to isolate and analyze proteins on the surface of extracellular vesicles.
This extremely simple video shows that a single drop can be flown into a mass spectrometer, in this case a JEOL TOF MS. This technology and related embodiments will to some extent, we predict, replace electrospray ionization as it shoots drops in a straight line as opposed to a spray. In a spray, coulombic repulsion of like charged drops limits the amount of matter (peptides, proteins and more in samples ) than can get into the MS system. This adversely reduces the sensitivity of MS when in fact it is not necessary if you use our patented technology, induction based fluidics. The simple video and the physics behind it will improve our ability to detect important biological molecules of interest (like cancer and other biomarkers and more, like large proteins) in their native state, at ph...

Bruker launched their new EVOQ series of LC Triple Quadrupole Mass Spectrometry systems at JASIS 2012. The EVOQ triple quadrupole for liquid chromatography (LC-TQ) was designed for a singular purpose - to reliably quantify thousands of real samples in the fastest sample-to-report time possible. It delivers exceptional sensitivity, precision, accuracy, linearity, and a wide dynamic range for you multiple reaction monitoring assays. Innovations in software and atmospheric pressure ionization (API) technology make it a game changer for routine high-sensitivity quantitative analysis.
