WEBINAR
Introduction This webinar will review PerkinElmer's atomic spectroscopy product portfolio relevant to mining. PerkinElmer’s portfolio of atomic spectroscopy solutions encompasses atomic absorption (flame, furnace and combined AA), ICP-OES, and ICP-MS as …
APPLICATION NOTE
Introduction This application note highlights the LC/MS/MS analysis of PFAS compounds according to the European Union Water Framework Directive 2020/2184. It demonstrates how the PerkinElmer QSight® 420 LC/MS/MS System using a large volume direct …
APPLICATION NOTE
Introduction Cyanotoxins often exist intracellularly in cyanobacteria and are released into the water when cells die. Blooms caused by cyanobacteria can be harmful to the human health, animals, and the environment. Microcystin-LR (MC-LR) is one of the …
APPLICATION NOTE
Introduction Emulsions are widely used across a variety of industries including agrochemicals, cosmetics and, importantly, pharmaceuticals. In recent years, emulsion-based adjuvants have been developed which have allowed for an improvement in …
APPLICATION NOTE
Introduction Quantification of RNA can be easily carried out exploiting the Beer-Lambert’s Law which defines the direct proportion between the concentration of a sample and the quantity of light absorbed. Based on the presence of purine and pyridine …
APPLICATION NOTE
Introduction UV/Vis spectroscopy represents a powerful technique to study any analyte that is able to absorb light in the UV and Visible region of the electromagnetic spectrum. When proteins contain aromatic side chain amino acids and disulfide bonds,1 …
APPLICATION NOTE
Introduction All pharmaceutical packaging systems need to comply with performance requirements to guarantee the integrity and safety of the contained drug throughout its lifecycle, from manufacturing to distribution and ultimately to the end-user. …
APPLICATION NOTE
Introduction Development of recombinantly expressed therapeutic proteins as biopharmaceuticals hold the great advantage of biocompatibility and biodegradability. The success of such protein-based drug formulation relies on a deep understanding of the …
APPLICATION NOTE
Introduction Contaminants in chemicals used during manufacturing processes have a direct impact on product yield and reliability of semiconductor devices. Within the whole process of integrated circuit manufacturing, wafers are sent for repeated …
APPLICATION NOTE
Introduction Microplastics are a major concern due to their impact on the environment. There is growing research into microplastics, typically submillimeter in size, and which often end up in waterways and oceans. They remain in a suspended state and …
APPLICATION NOTE
Introduction Normally, thermoplastic materials are utilized as the raw material of 3D printers, while more advanced and sophisticated prototype uses the precursor of thermoset materials (or a prepreg) as the feedstock sources. Due to the reaction nature …
WEBINAR
Introduction Infrared microscopy provides a rapid and non-destructive means for investigating the composition of trace evidence, including paint chips. Spectral data can be used to evaluate possible links between suspects and victims. This presentation …
APPLICATION NOTE
Introduction Nitrite, occurs naturally in the environment as an intermediate of the nitrogen cycle through microbial decomposition of organic matter. However, nitrite contains nitrogen in a reasonably unstable oxidation state and readily oxidizes to …
WEBINAR
Introduction From the electronics we interact with daily and increasingly the vehicles we travel in, lithium-based batteries are required in greater quantities with higher quality control requirements. Understanding the materials and components used in …
APPLICATION NOTE
Introduction Sodium hypochlorite is one of the most common disinfectants used in both domestic and commercial settings and has been included on the environmental protection agency (EPA) list of disinfectants recommended for use against COVID-19. This …
APPLICATION NOTE
Introduction Infrared microscopy is a well-established analytical technique for the measurement and identification of small samples down to a few micrometers in size. It is used extensively in the polymer, pharmaceutical, chemical, food, and electronics …
APPLICATION NOTE
Introduction The primary goal of this technical note is to guide the user through the accessory selection process for different specular/ diffuse samples. This will be achieved by measuring identical samples with varying contributions of diffuse and …
APPLICATION NOTE
Dynamic Mechanical Analysis (DMA) is a technique used to investigate the stiffness of materials as a function of temperature, humidity, dissolution media or frequency. A mechanical stress is applied to the sample and the resultant strain is measured by …
APPLICATION NOTE
Introduction Thermogravimetry has been used for years to quantify the components of automotive rubber products, namely oil, polymer, carbon, and inorganic filler. While this separation is straightforward conceptually, it challenges the performance of …
APPLICATION NOTE
Introduction Paint manufacturers are interested in the reflectivity of their products. This characteristic involves properties in both the visible region where color is important as well as extending into the Near Infrared (NIR) region where the …
ARTICLE
Selecting a staffing and service maintenance model for your food testing laboratory lab is no easy task. With a myriad of different lab characteristics and goals, one size never fits all. How do you determine which model is the right fit for your lab? … …
APPLICATION NOTE
Introduction Internal combustion in an engine produces soot as a result of incomplete fuel combustion. The soot deposits deplete the quantity of dispersant additives which may cause an increase in viscosity which in turn increases engine wear. These …
APPLICATION NOTE
Introduction Residual solvents are used in the manufacture of active pharmaceutical ingredients (APIs), excipients, or in preparation of drug products, and are not removed during the purification processes. Residual solvents are one of the three main …
APPLICATION NOTE
Introduction Acetaminophen and aspirin are the drugs of choice used to relieve the symptoms of common headache. Acetaminophen, which is also called paracetamol, is widely used as a pain reliever (analgesic) and fever reducer (antipyretic). Because of …
APPLICATION NOTE
Introduction The synthesis of active pharmaceutical ingredients(API) may require multiple reaction steps that produce undesirable reaction byproducts or utilize various solvents that have to be removed from the finished product. These solvents and …
