    Water Analysis Using LAMBDA UV/Visible Spectrophotometers: Iron Determination

    Iron is rarely found in its elemental form in nature due to the high tendency of its ions, Fe(II) and Fe(III), to form oxygen and sulphur containing compounds. Concentrations of iron found in surface waters are typically no greater than 1 mg/L, unless contaminated by industrial effluents, whilst much higher concentrations are found in ground waters. The World Health Organization guideline for iron in drinking water is 0.3 mg/L as undesirable bacteria growth in water systems occurs above this concentration. In this application, the quantitative analysis of iron was performed using the LAMBDA 265™ UV/Vis spectrophotometer and CHEMetrics iron cell test kit.

    Data Integrity - UV WinLab Enhanced Security (ES) Software for UV/Visible Spectroscopy

    The FDA defines data integrity as "completeness, consistency, and accuracy of data. Complete, consistent, and accurate data should be attributable, legible, contemporaneously recorded, original or a true copy, and accurate (ALCOA)". ALCOA itself has evolved to ALCOA Plus, which incorporates two of the fundamental definition terms as stated by the FDA; complete, consistent, enduring, and available. Compliance with 21 CFR Part 11 is mandatory for pharmaceutical companies and their suppliers to sell products into the United States, and also applies to other related industries.

    PerkinElmer's UV WinLab Enhanced Security (ES) software platform for UV/Visible spectroscopy provides structural requirements and features to assist with the needs for ensuring data integrity and compliance. It affords the system owner the ability to comply with regulations and incorporate features into the validation plan to exhibit compliance. The purpose of this document is to demonstrate how UV WinLab ES meets the technical requirements for 21 CFR Part 11.

    Water Analysis Using LAMBDA UV-Visible Spectrophotometers: Chemical Oxygen Demand Determination

    Chemical Oxygen Demand (COD) is used as an indirect measurement of the sum of oxidizable matter in water and measures the equivalent amount of oxygen required to oxidize organic compounds. Wastewater commonly contains organic compounds, as a result of industrial processes, which can oxidise in the presence of dissolved oxygen in the water. Low levels of dissolved oxygen can be detrimental to aquatic life but high levels may cause corrosion of metal pipes. It is important to use COD as an indicator of water quality. In this application, quantitative analysis of COD was performed using the LAMBDA 265TM UV-Vis spectrophotometer and Merck Spectroquant® COD mercury free cell test.

    Water Analysis Using LAMBDA UV-Visible Spectrophotometers: Nitrite Determination

    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 nitrate. As a result, nitrite is present at considerably lower concentrations in ground and surface waters than nitrate1. Higher concentrations of nitrite are indicative of pollution by industrial wastewater or agricultural run-off. In this application, the quantitative analysis of nitrite-nitrogen was performed using the LAMBDA™ 265 UV-Vis spectrophotometer and CHEMetrics nitrite test kit.

The Merck test kit allows the concentration to be determined without the use of a calibration curve by multiplying the measured absorbance at 340 nm by a known factor. In this application, the quantitative analysis of nitrate was performed using the LAMBDATM 265UV-Vis spectrophotometer and Merck Spectroquant® cell test. The method used is analogous to DIN 38405-9.

    Water Analysis Using LAMBDA UV/Visible Spectrophotometers: Ortho-Phosphate Determination

    In surface waters, phosphorus commonly exists in its phosphate form. A high concentration of phosphate in water is indicative of domestic waste, industrial effluent, and agricultural runoff which can lead to eutrophication. Eutrophication causes an increase in plant and algal growth, which decreases the dissolved oxygen in the water, often leaving the water uninhabitable to organisms. In this application, the quantitative analysis of ortho-phosphate was performed using the LAMBDA 265 UV/Vis spectrophotometer and CHEMetrics ortho-phosphate cell test kit.

  • Application Note

    Measurement of Gold Nanoparticle Solutions on the LAMBDA 265

    The data shows the suitability of the LAMBDA 265 for producing rapid, high-quality spectra. It also shows that the instrument is able to measure the higher nanoparticle sizes, even though these scatter light to a greater extent due to the increased particle size and also settle out more quickly.

  • Application Note

    Water Analysis Using LAMBDA UV/Visible Spectrophotometers: Ammonia-Nitrogen Determination

    Ammonia-nitrogen (NH3-N) occurs naturally in groundwaters at concentrations below 0.2 mg/L and up to 12 mg/L in surface waters, as a result of decomposition of organic matter. High concentrations of ammonia in surface waters are toxic to aquatic life and are indicative of contamination from industrial effluent, raw sewage and agricultural runoff. Ultimately the pH value of the water determines whether ammonia-nitrogen is found as NH4+, NH4OH or NH3. 1 In this application, the quantitative analysis of ammonia-nitrogen was performed using the LAMBDA 265™ UV/Vis spectrophotometer and CHEMetrics ammonia nitrogen cell test.

  • Application Note

    Gaining high resolution measurements of optical filters in the NIR range with the LAMBDA 1050 UV/Vis/NIR

    Monitoring Fast Chemical Reactions Application Note

    Spectrosopic techniques, such as UV-Visible spectrometry, can be deployed to observe the chemical changes taking place during fast reactions. However, in many cases the reaction timescales are too fast to be performed and observed by the simple manual mixing of the reactants in a cuvette. The stopped-flow technique is frequently used for rapid kinetics experiments allowing the reactants to mix effectively and react whilst monitoring the reaction in a low volume cuvette in the UV-Visible instrument. This application note demonstrates how the PerkinElmer LAMBDA 465 Diode Array UV-Visible Spectrophotometer together with the TgK Scientific SFA-20 Rapid Kinetics Accessory allows reaction monitoring on the millisecond timescale.

    Measuring Absorptance (k) and Refractive Index (n) of Thin Films with the PerkinElmer LAMBDA 1050+ High Performance UV/Vis/NIR SpectrometersUV/Vis Spectroscopy

    An optical coating consists of a combination of thin film layers that create interference effects used to enhance transmission or reflection properties for an optical system. How well an optical coating performs is dependent upon the number of factors, including the number of layers, the thickness of each layer and the differences in refractive index at the layer interfaces. The transmission properties of light are predicted by wave theory. One outcome of the wave properties of light is that waves exhibit interference effects. Light waves that are in phase with each other undergo constructive interference, and their amplitudes are additive. Light waves exactly out of phase with each other (by 180°) undergo destructive interference, and their amplitudes cancel. It is through the principle of optical interference that thin film coatings control the reflection and transmission of light.
