  • METHOD 3051 MICROWAVE ASSISTED ACID DIGESTION OF SEDIMENTS, SLUDGES . . .
    Any vessels containing 10 mL of nitric acid for analytical blank purposes are counted as sample vessels When fewer than the recommended number of samples are to be digested, the remaining vessels should be filled with 10 mL of nitric acid to achieve the full complement of vessels
  • TN44483 Sample prepration guide for trace elemental samples
    Weigh 0 5 g of sample into a microwave digestion vessel and add 10 mL of concentrated HCl and 2 0 mL of concentrated HNO 3 Seal the vessel and digest at 180 ̊C for 20 min
  • MICROWAVE ASSISTED DIGESTION
    This standard operating procedure (S O P) describes the microwave-assisted acid digestion of aqueous and solid samples, with guidelines from EPA method 3015A for aqueous samples and EPA method 3051A for sediments, soils, sludges, and oils
  • Method 3031: Acid Digestion of Oils for Metals Analysis by Atomic . . .
    The sample is then treated with 2 mL concentrated nitric acid 10 mL of c oncentrated HCl is added and the sample is heated until the reaction is complete and is then filtered
  • Microwave Digestion for ICP Analysis - Anton Paar Wiki
    Dedicated microwave digestion systems feature an built-in method library that suggests the sample weight, acid mixture, and a temperature time program to successfully digest various samples
  • CEM Microwave Digester Protocol - Arizona State University
    Before proceeding to microwave digestion of your samples please consult the “ICP-OES target detection range” or other appropriate instrumentation documentation to be sure you are digesting the appropriate mass for detection levels for the analysis
  • Sample preparation II
    Organic sample materials are generally decomposed and completely mineralized into carbon dioxide with the aid of oxidizing acids (primarily nitric acid) and reagents (primarily hydrogen peroxide)
  • Microwave Acid Digestion of Crude Oil Samples Using a New High . . .
    A mix of crude oil samples and NIST 1634c (Trace Metals in Fuel Oil) will be prepared and analyzed for As, V and Ni A One Touch MethodTM was created with a target temperature of 240 °C and a 20 min hold
  • Microwave digestion - NDSU
    Typical method parameters: Small sample size: powdered samples facilitate digestion maximum 250 mg for organic samples (e g plants, animal tissue) maximum 500 mg for inorganic samples (e g soils) Extraction volume: minimum 5 ml, typically 10 ml Acid solution: typically nitric acid, hydrochloric acid, aqua regia or acid+water
  • Method 3015A: Microwave Assisted Acid Digestion of Aqueous Samples and . . .
    If the weight loss of the sample exceeds 1% of the weight of the sample and reagents, then the sample is considered compromised For vessels with burst disks, a careful visual inspection of the disk, in addition to weighing, may identify compromised vessels
