Interlaboratory comparison of magnetic thin film measurements

Journal of Research of the National Institute of Standards and Technology, 2003
A potential low magnetic moment standard reference material (SRM) was studied in an interlaboratory comparison. The mean and the standard deviation of the saturation moment m s, the remanent moment m r, and the intrinsic coercivity H c of nine samples were extracted from hysteresis-loop measurements. Samples were measured by thirteen laboratories using

A Common Reference Material for Mass‐Dependent Sn Isotope Compositions: An Inter‐Laboratory Calibration Approach

Geostandards and Geoanalytical Research, EarlyView.
Key Points We recommend using the notation δ122/118SnNIST SRM 3161a for mass‐dependent Sn isotope data. We derived conversion factors relative to NIST SRM 3161a for Puri Sn CEZA (0.132 ± 0.011‰), Sn Lyon (0.229 ± 0.016‰), Sn IPGP (0.162 ± 0.018‰). Tin isotope compositions are presented for SPEX CertiPrep Sn and nine USGS reference materials.

Dysplasia in sessile serrated lesions: frequency, interobserver variability and added value of immunohistochemistry

Histopathology, EarlyView.
Sessile serrated lesions with dysplasia represent a critical step in colorectal carcinogenesis. While routine histologic diagnosis is generally reliable and positive diagnostic trends are observed, subtle dysplastic changes may be overlooked. Targeted use of MLH1 immunohistochemistry provides meaningful diagnostic support in selected sessile serrated ...

Fluorination of Silver Phosphate in Nickel Reaction Vessels for Triple Oxygen Isotope Analysis

Rapid Communications in Mass Spectrometry, Volume 40, Issue 7, 15 April 2026.
ABSTRACT Rationale Increasingly, more laboratories are measuring the triple oxygen isotope values of phosphate. Standardization is key to having good interlaboratory results. Here, we present the triple oxygen isotope values of a suite of standards using fluorination and compare them with previously reported triple oxygen isotope values. Methods Silver

The Evaluation of Machine Learning Models Using Matrix‐Assisted Laser Desorption/Ionization Time‐of‐Flight Mass Spectrometry (MALDI–TOF–MS) Spectra for the Prediction of Antibiotic Resistance in Klebsiella pneumoniae

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
Machine learning models developed from matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry spectra can rapidly predict antimicrobial resistance in Klebsiella pneumoniae. By transforming routine spectral data into accurate resistance profiles within minutes, this approach could reduce diagnostic delays and support earlier ...

Multi‐Solvent Suppression Ultrafast 2D COSY for High‐Throughput Wine Screening

Magnetic Resonance in Chemistry, Volume 64, Issue 4, Page 416-426, April 2026.
An interleaved ultrafast COSY with multi‐solvent suppression was developed for wine analysis to overcome limitations often associated with 1D 1H NMR (signal overlap) and conventional 2D NMR (long acquisition times) methods. Within an acquisition time of ~20 min, it revealed hidden metabolite peaks and cross peaks for improved annotation and ...

The PNH French Working Group Experience: Building a Strong Network of Cytometrists

International Journal of Laboratory Hematology, Volume 48, Issue 2, Page 242-249, April 2026.
ABSTRACT Introduction The PNH working group was created in 2010 to initiate a workshop on testing white blood cells to share international recommendations. Methods Thirty‐five French and Belgian laboratories equipped with 2‐ or 3‐laser cytometers applied three different panels with or without FLAER reagent in 305 samples.
