Atomic spectroscopy standard

Manufactured by PerkinElmer
Visit Supplier
Sourced in United States

Atomic spectroscopy standard is a reference material used for the calibration and performance verification of atomic spectroscopy instruments, such as atomic absorption (AA), atomic emission (AE), and inductively coupled plasma (ICP) spectrometers. It provides a known concentration of specific elements to ensure accurate and reliable analytical results.

Multielement Digestion and Calibration

The reagents used in the digestion procedures were: nitric acid (67%, NORMATOM®, Ultrapure, VWR Chemicals, Radnor, PA, USA), perchloric acid (65–71%, NORMATOM®, Ultrapure, VWR Chemicals, Radnor, PA, USA) and hydrogen peroxide (30%, NORMATOM®, Ultrapure, VWR Chemicals, Radnor, PA, USA). High-purity Milli-Q water (Merck Millipore Milli-Q, Burlington, MA, USA) was employed in all the steps that required its use.
Calibration curves were constructed using multielement external standards. These were prepared starting from 1000 mg L−1 single-element standard solutions (Perkin Elmer Pure, Atomic Spectroscopy Standard, Shelton, CT, USA).

All chemicals were of analytical grade reagent. Atomic spectroscopy standard (Perkin Elmer, USA) stock Cu(II) solution (1000 μg/mL) was used and diluted to the desired value. All required metal solutions were obtained from their respective nitrate salts and ICP standards as Ni, Mn, Zn, Cd, Pb, Co, Cr, and Cu(NO3)2 (Merck, Germany). Activated carbon (Sigma-Aldrich, USA), hydrazine hydrate (Merck, Germany), HNO3 (65%, Merck, Germany), NaOH (Merck, Germany), HCl (37%, Merck, Germany), ethanol (Merck, Germany), and N-methoxymethyl melamine chemical basis a crosslinker (RUCO-COAT FX 8000, Rudolf Duraner, Bursa, Turkey), ethylendinitrilo tetraacetic acid, disodium salt dihydrate (Titriplex III) (Merck, Germany) were used in the experiment. NIST 1643e and soft drinking water (certified reference material) obtained from National Institute of Standard and Technology, (Gaithersburg, USA).

Trace Metal Analysis in Fish Tissue

Check if the same lab product or an alternative is used in the 5 most similar protocols
Quality was monitored through analysis of procedural blanks, duplicate samples, and standard solutions. Standard solutions of analytes were prepared from certified stock solutions of Cd, Pb, and Hg with a relative matrix modifier (atomic spectroscopy standard, Perkin Elmer). Concentrations for each set of samples were determined in the medium range of the calibration curve.
The performance of the method was assessed through participation in interlaboratory studies organized by FAPAS (Food Analysis Performance Assessment Scheme, Sand Hutton, UK). The FAPAS studies were conducted with fish tissue. The limit of detection (LOD) and the limit of quantification (LOQ) were calculated by determining the standard deviation of 10 independent blanks spiked at 1, 2, 4 and 8 µg g−1 for Cd and 25, 50 and 100 µg g−1 for both Pb and Hg, with an external standardization curve [20 (link),21 (link),22 (link)].

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
