Introduction Rice is one of the most commonly consumed foods in the world. A variety of pesticides have been used in rice production to control pests, weeds and diseases to increase crop yield. Pesticides applied in rice crops are often country/region …
APPLICATION NOTE
Introduction This study was to measure the levels of PAHs concentrated on the surface of microplastic particles in order to begin to understand the risk to the marine biological ecosystem. This work demonstrates the fast, effective chromatographic …
APPLICATION NOTE
Introduction Perfluorinated compounds (PFCs) have received lots of attention recently due to their resistance to degradation in the environment. Reports of their occurrence in tap water, food or even human blood have led to concerns of their impact on …
APPLICATION NOTE
Introduction Liquid chromatography-tandem mass spectrometry (LC/MS/MS) has become the method of choice for pesticide. The state of Oregon has issued regulatory limits for 59 pesticide residues in both cannabis flower and concentrates, while other states …
APPLICATION NOTE
Introduction One of the most challenging analytical problems with increasing importance is the possibility to analyze soil polluted by the dispersion of organic fluids which sometimes features particularly high boiling points. The current techniques …

Analysis of Drug Substances in Common Cold Medicines with the PerkinElmer Flexar FX-15 System Equipp
Introduction The misuse of cold remedies can be prevented by appropriate medical indications and accurate label claims. To that end, the U.S. Food and Drug Administration and the pharmaceutical industry have made it a standard procedure to routinely …
APPLICATION NOTE
Introduction The analysis of all incoming pharmaceuticalraw materials is a key part of 21CFR compliance (section 211.84). It is therefore important to have a high-throughput method by which raw materials may be analysed in a loading bay or …
APPLICATION NOTE
Introduction In materials research there is sometimes a need to scan high absorbance samples such as laser protection lenses, optical filters, and polarization materials. Such sample types often need to be measured across the whole UV, Vis and NIR …
APPLICATION NOTE
Introduction Building or Architectural glass products control the amount of light and heat entering a building, offering safety and security, insulation against noise, providing privacy, comfort and decoration. Building glass products can play a vital …
APPLICATION NOTE
Introduction The EU Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) regulation was adopted in 2006 with the aim of protecting human and environmental health, along with the competitiveness of the chemical industry within the …
APPLICATION NOTE
This application note demonstrates the ability of Dynamic Mechanical Analysis (DMA) to characterize the mechanical properties of an epoxy based printed circuit board (PCB) using a PerkinElmer® DMA 8000. The modulus of the PCB is measured providing an …

APPLICATION NOTE
Introduction With the development of nanotechnology and the increased use of nanoparticles (NPs) in numerous products and processes, the need to characterize them has also grown. Nanoparticles come in a wide variety of compositions, with silica dioxide …
APPLICATION NOTE
Introduction To better understand the impact of nanoparticles, several key characteristics need to be assessed, such as concentration, composition, particle size, shape and other surface characteristics. The NexION® SP-ICP-MS, with Syngistix™ Nano …
APPLICATION NOTE
Introduction With the increasing use of nanomaterials in a wide variety of products and processes, the need to measure and characterize them has also grown. Single particle ICP-MS (SP-ICP-MS) was developed specifically for metallic and metal-containing …
APPLICATION NOTE
Introduction For decades, the semiconductor industry has been designing new devices that are smaller, faster and consume less power than their predecessors. To maintain this trend, the critical features of these devices must also become smaller and have …
APPLICATION NOTE
Optical filters have many functions, including color correction, used to improve color balance in many optical systems, to neutral density filters that produce specific reduction in the level of transmitted light. The characterization of these diverse …
APPLICATION NOTE
Introduction When mining for precious metals, ores are extracted from the ground and subjected to various sample preparation procedures in order to remove the metals of interest. A commonly used procedure to isolate metals from the ore is fire-assay, …
APPLICATION NOTE
Introduction Elemental analysis of fuel oil is an important step in quantifying its quality. Combustion of fuels containing metals can lead to the formation of low melting-point compounds that are corrosive to metal parts. The presence of certain …
APPLICATION NOTE
Introduction Thermogravimetric analysis (TGA) is a common technique that is used to study the weight loss during heating. It can tell you the percentage of weight loss quantitatively and accurately. But TGA alone will not tell you anything about the …
APPLICATION NOTE
Introduction For many years, inductively coupled plasma mass spectrometry (ICP-MS) has been the tool of choice for the trace analysis of elements like lead (Pb), arsenic (As), mercury (Hg), and copper (Cu) in bodily fluids such as urine, blood, serum …
APPLICATION NOTE
Introduction In the “Early Drug Discovery Phase” of pharmaceutical development when there is a minimum amount of synthesized drug candidate, quick thermal analysis using a small amount of sample is the norm. The sample amount could be less than 3 mg. …
APPLICATION NOTE
Introduction Increasing the sensitivity and throughput of Differential Scanning Calorimetry (DSC) analysis has always been a challenge for thermal analysts in research and development. DSC analysis becomes difficult for small sample sizes, high …
