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 …
WHITE PAPER
Introduction Fertilizer and agrochemicals industries have a long history of innovation that has helped improve food availability and quality for the world. Today, the industry faces new challenges around the increasing need for food, decreasing …
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 …
APPLICATION NOTE
Introduction Compliance with California’s Proposition 65 for the monitoring of lead (Pb) in calcium-based antacid medications and dietary supplements requires the analytical methodology to demonstrate detection limits below 0.05 µg/g in the solid …
APPLICATION NOTE
Introduction Counterfeiting of pharmaceuticals and the proliferation of substandard drugs constitute a serious health risk for the world population, including both industrialized and developing countries. It is estimated that five to eight percent of …
APPLICATION NOTE
Introduction Urine is the matrix of choice as it can be collected easily and in large volumes. The variations within the urine matrix can adversely impact chromatographic separation and LC-MS/MS signal. The present study demonstrates that a simple …
WEBINAR
IR Microscopy That Overcomes Your Biggest Challenges And Your Smallest … Introduction PerkinElmer Spotlight™ 150i and 200i are high-performance FT-IR microscopy systems designed to meet the needs of lab scientists faced with analyzing increasingly …
APPLICATION NOTE
Introduction Measurement of metanephrines and normetanephrine in plasma is challenging due to the low physiological concentrations, their hydrophilic nature1, and time consuming traditional sample preparation. With use of the PerkinElmer QSight® 220 …
APPLICATION BRIEF
Introduction Inductively coupled plasma mass spectrometry (ICP-MS) is the technique of choice for the analysis of food materials. This is thanks to its ultratrace detection capabilities, ideal for the determination of low-level contaminants, such as Pb, …
APPLICATION BRIEF
Introduction Compositional analysis of liquid animal feed is an important step in verifying proper nutritional value at the mixer and prior to shipment to customers. Nutritional information is vital to farmers when formulating feeding strategies. The DA …
APPLICATION NOTE
Introduction Explosive materials are composed of energy-rich substances that release stored energy through a series of violent chemical processes upon ignition. The chemicals responsible for these explosive reactions are typically unstable without the …
APPLICATION NOTE
Introduction The production of fertilizer is a key industry for a country's agricultural sector, with the main benefit of increasing crop productivity. The primary elements of interest in fertilizers are categorized into four classes: primary nutrients, …
APPLICATION NOTE
Introduction Pharmaceutical and Personal Care Products (PPCPs) are an emerging environmental concern, and include human and veterinary prescription and over-the-counter medications, sunscreens, lotions, soaps, and insect repellants. These commonly …
APPLICATION NOTE
Introduction Volatile organic compounds (VOCs) are a series of compounds with high vapor pressure and boiling points from 50 to 250 degrees centigrade. These characteristics lead to the tendency for large numbers of molecules to evaporate, or …
APPLICATION NOTE
Introduction Aniline and aniline derivatives are widely used as raw materials and intermediates in the polymer, rubber, dye, pesticide and pharmaceutical industries. Unintended releases of aniliane or its derivatives into the environment pose a serious …
APPLICATION NOTE
Introduction When blending base oils and additives for use as lubricants, it is important to know and control the concentrations of certain elements for optimal performance and longer engine life. Because this process is so crucial, ASTM developed a …
APPLICATION NOTE
Introduction With heavy machinery, it is important to assess its status during operation to prevent breakdowns and costly repairs. A key aspect is monitoring the status of the oil or lubricants used to lubricate various components such as engines, …
