The service is applicable for active pharmaceutical ingredients APIsproprietary chemicals, industrial chemicals and intermediates, nanomaterials, as well as products in the client development pipeline. Before considering method development, check with the laboratory to see if a method for your sampling target is already available by consulting the Maxxam sampling guide.

If an application is found, assess the details to see if it meets the requirements of your sampling plan. What is involved with Method Development? We can also meet client requirements for U.


Following the applicable guidelines, protocols can be customized to meet your project validation requirements. Validation of existing methods Maxxam can provide validation services on existing methods including method transfer, validation, verification and storage stability.

Our experts can remediate existing methods to bring those techniques up to current validation practices, extend the range or fill gaps in the original validation. View our range of available validation protocols.

Partnering With Maxxam The Maxxam industrial hygiene laboratory offers the most advanced instrumentation technologies and more than 80 professional staff, including certified industrial hygienists CIHchemists Ph.

Between our laboratories, we have developed more than sampling and analytical methods over the last two decades. In the field of Microscopy, we have a professional geologist who was an author and technical contact for method ASTM D, for analysis of asbestos in a soil matrix.

As a starting point for method development, we require: At the completion of the project, we provide a comprehensive analytical method and validation report, documenting analytical parameters, the sample preparation procedure, and results for the individual studies.

Surface Contamination To measure potential surface contamination, Maxxam has successfully adapted industrial hygiene analytical methods in order to address surface sampling, for housekeeping purposes.

Analysis can be performed from swipes, swabs, or rinses. These methods are intended to evaluate only the surface sampling and other procedures that differ from air sampling methods.Sulfuric acid (alternative spelling sulphuric acid), also known as vitriol, is a mineral acid composed of the elements sulfur, oxygen and hydrogen, with molecular formula H 2 SO benjaminpohle.com is a colorless, odorless, and syrupy liquid that is soluble in water, in a reaction that is highly exothermic..

Water Quality and Pollution

Its corrosiveness can be mainly ascribed to its strong acidic nature, and, if at a high concentration. Also referred to as acid rock drainage (ARD), AMD emanating from mine waste rock, tailings, and mine structures, such as pits and underground workings, is primarily a function of the mineralogy of local rock material and the availability of water and oxygen.

Michael Rog supervises the Method Development and Validation group at the Lake Zurich Industrial Hygiene laboratory. He earned his B.S. in Biochemistry from the University of Illinois at Chicago and a Masters in Analytical Chemistry from Northeastern Illinois University. PARTICIPANT’S MANUAL.
