Vaccines and biopharmaceutical products are typically proteins, viruses or viral particles which require complex production systems, in most cases involving application of recombinant DNA technology. Some of these bioproducts, which are less complex in terms of post-transcription transformation (glycolyation, phosphorylation, disulphate bridges, and amidation, etc.) can be produced in yeasts Read more…
IPT is specialized in the culture of microorganisms of scientific, industrial and environmental interest. Microorganisms are preserved in lyophilized form, by ultra-freezing at -80°C and other alternative methods for specific strains. The Institute has a collection containing a variety of microorganisms for control, monitoring and validation (sterilization tests, autoclave validation, Read more…
Microencapsulation involves a group of specific techniques that allow for the preparation of functional particles, and consists of a support material (encapsulating agent) and an active compound distributed in its core. Microencapsulation technology requires extremely strict control of specific properties of the product, whose action is programmed or controlled. IPT Read more…
Examples of products in which contaminants have been identified include: automotive parts and vehicles beverages, food and others filters showing abnormally high concentrations of residues or sediments raw materials packaging textiles, papers, plastics and others industrial process wastes plastics with liquid coatings IPT characterizes contaminants in different materials, using infrared Read more…
Paper, textiles, and materials in powder and liquid readily absorb and retain odors, some of them difficult to characterize but perceptible to the human sense of smell. IPT’s laboratories are prepared to identify substances that can cause unusual odors in different types of materials, by comparing an odorless material of Read more…
IPT performs tests to determine the distribution of fatty acids in different materials such as soaps, vegetable and animal oils and mixtures, among other materials. The techniques it employs include derivatization (transformation of acids into methyl esters), mass spectrometry for identification and gas chromatography for quantification of the methyl esters Read more…
IPT determines the chemical composition of solvents based on official standards or procedures requested by clients. The components are identified by mass spectrometry or injection of standards by gas chromatography, a technique which is also used to quantify the components. Determination of the chemical composition enables one to: Find the Read more…
Methyl bromide has been used in fumigation processes to control pests that infest wooden pallets and some crops. Although it is a gaseous material, after fumigation some residues of methyl bromide may be left in wood treated with this fungicide. Methyl bromide is highly toxic and its use is gradually Read more…
IPT determines Polycyclic or Polynuclear Aromatic Hydrocarbons (PAHs) in raw materials, finished products and subproducts of metalworking companies, steel mills, petrochemical plants and chemical transformation industries in general, in order to overcome technical barriers to exportation. This analysis is also required for purposes of occupational health control, since some PAHs Read more…
