Check the solubility of 128 common inorganic compounds (salts and acids) in water at different temperatures from 0 degrees Celsius to 100 C. Compound formulas are also given in this table of solubility in relation to temperature.
Download the Periodic Table of the Elements with names, atomic mass and number in printable .pdf and image format. Use the periodic table chart by element names in alphabetical order for quick research, reference and lab use.
Sigma-Aldrich presents an article about the analysis of melamine and related compounds in dog food with the use of more economical gas chromatography-mass spectrometry (GC-MS) instrumentation.
Ionic Liquids have experienced a comet-like boost in the last few years. In this edition of ChemFiles, we highlight some current applications of this fascinating class of new materials. We present over 50 new additions to our portfolio of 130+
Samples for chromatographic purification should be clear and free from particulate matter. Simple steps to clarify a sample before beginning purification will avoid clogging the column, can reduce the need for stringent washing procedures, and can extend the life of
Pesticide residue testing of turmeric and other (dried) spices is challenging due to their complex compositions and high matrix. An efficient SPE clean-up can be achieved by a new Dual-layer cartridge.
The odor and pungency of ginger is due to the presence of terpenes, gingerols and shogaols. These compounds contribute to the highly complex matrix of ginger, which subsequently presents a challenge in low level analyses of contaminants. A novel 2-layer
Research evaluating immune checkpoints may help identify those likely to benefit from PD-1/PD-L1 immunotherapy and reveal new immunotherapy targets for future investigation. See how the MILLIPLEX® Human Immuno-Oncology Checkpoint Protein Panel 2 was used to multiplex immune checkpoint molecules for
Local delivery of bioactive molecules using an implantable device can decrease the amount of drug dose required as well as non-target site toxicities compared to oral or systemic drug administration.
This page clarifies sample preparation, buffer exchange and desalting, removal of lipoproteins, phenol red, and low molecular weight contaminants in Ion exchange chromatography.
Affinity chromatography is the process of bioselective adsorption and subsequent recovery of a compound from an immobilized ligand. This process allows for the highly specific and efficient purification of many diverse proteins and other compounds. The process requires
Professor Shinar (Iowa State University, USA) summarizes the developments of a variety of sensor configurations based on organic and hybrid electronics, as low-cost, disposable, non-invasive, wearable bioelectronics for healthcare.
Graphene is a unique two-dimensional (2D) structure of monolayer
carbon atoms packed into a dense honeycomb crystal that has attracted
great interest due to its diverse and fascinating properties.
Optimizing the synthesis of high-quality 2D MXene flakes for 3D ink printing is essential to such technological developments as printable and flexible electronics.
Poly(2-oxazoline)s (POx) can be viewed as conformational isomers of polypeptides. They are synthesized via living cationic ringopening polymerization (LCROP) of 2-oxazolines and were almost simultaneously discovered in 1966 by the groups of Litt, Tomalia, Fukui and Seeliger.
Cell lines for vaccine production and cultivation of SARS CoV-2 and other viruses. Primary, human diploid, and continuous culture cell lines for the propagation of viruses and virus-based vaccines.
Immunohistochemistry (IHC) techniques and applications have greatly improved, dermatopathology is still largely based on H&E stained slides.This paper outlines ways in which IHC antibodies can be utilized for dermatopathology.
