SPE stuck? Your sample won’t flow through the cartridge? You’re not alone. Genevie Hodson, Senior Manager of Technical Support and Applications at Phenomenex, shares a step-by-step way to fix it.

• First, time the issue ⏱️: during conditioning/blank, during loading, or after loading?
• Viscous or cloudy samples 🥣: Dilute, centrifuge, filter—or use larger particles (Strata XL 100 µm vs Strata-X 33 µm).
• Low manifold pressure 🧰: Check the manifold, instrumentation, and individual positions.
• Immiscible solvents 🚫💧: Use only mutually miscible pairs (avoid hexane with water).
• Precipitation/proteins 🧪: Dilute, reduce volume, avoid denaturing solvents, pre-wash with a low ionic strength buffer.

• Pro tip 💡: Change one variable at a time to isolate the root cause.

Restore flow, reduce downtime, and keep your SPE running smoothly.

Troubleshoot SPE flow problems by identifying common causes such as viscous samples, manifold pressure issues, solvent incompatibility, and precipitation.

🔍 Demystifying PT statistics for better lab decisions

Eurachem’s leaflet explains how PT providers set the assigned value (xpt), its uncertainty u(xpt), and the standard deviation for proficiency assessment (σpt) — helping laboratories interpret PT reports with confidence.

• 📌 Location: choose the right estimator (mean, median, or robust per ISO 13528); robust methods shine with outliers or asymmetry.
• 📊 Dispersion: assess spread via SD or robust options (MADe, nIQR, Algorithm A, Qn, Q); beware small sample sizes.
• 🎯 Uncertainty of location: know when the mean is reliable; ISO 13528 suggests a conservative 1.25 factor with robust SD.
• 🧪 Methods matter: mixed analytical methods may justify method-specific locations.
• ⚠️ Quality checks: remove outliers before using classical mean/SD.

Guidance aligns with the Eurachem Guide (eds. B. Brookman, I. Mann) and ISO 13528:2022. Smarter PT choices start with the right stats. ✅

Understand the key statistical parameters used in proficiency testing schemes, including assigned values, uncertainty, and dispersion estimates.

🚀 NIST 26 elevates accurate‑mass GC‑MS processing. In a new guide and video, James Little (Mass Spec Interpretation Services) shows how the Chromatogram Window replaces standalone AMDIS for high‑resolution data—without sacrificing its proven deconvolution.

• 🔬 Unified workflow: deconvolution + library searching + accurate‑mass handling in one place.
• 🧠 Smart encoding: accurate‑mass ions → integer for AMDIS → back to m/z, yielding cleaner spectra, especially for trace analytes.
• ⚙️ Practical steps: set EI/Tandem and save .ini; 📂 load CDF/JDX; 🔎 search MainLib/RepLib (and Wiley); ⏱️ optimize scan combination (Maximum/Moderate/Fastest); run and review.
• 📈 Faster, clearer review: switch to log scale, sort by Relative Abundance, select >1% hits, and use Best Hits/Merge Duplicates/Filter Score; watch Max2Med for spectral reliability.
• ✅ Confidence check: send hits to MS Interpreter from the results table to verify fragments, formulas, and ppm errors; then 🧾 copy selected hits to Excel for reporting.

Result: simpler identification, better low‑level detection, and flexible reporting—an advance over standalone deconvolution for high‑resolution GC‑MS.

A practical guide to accurate-mass GC-MS processing in NIST 26, including deconvolution, library searching, spectral validation, and reporting.

Micro-Snyder Column vs Nitrogen Blowdown? In this clear comparison, David Oliva (Organomation) shows how to choose the right concentration method for EPA workflows. ⚗️📊

• Micro-Snyder (60–65°C): visual “chattering balls” = standardized, reproducible, high-throughput; used in EPA 625, 610, 607, 3570. ✅
• Trade-offs: higher glassware/heat investment, less real-time control. 💸⚠️
• Nitrogen blowdown (30–35°C): gentler for heat‑sensitive analytes (PFAS), precise volume endpoints, lower capital needs. 🌡️🎯
• Validated in EPA 3535A, 1668, 1699, 533, 537.1; baths often 30–60°C. 📄
• Caveats: constant attention required; avoid dryness (e.g., organophosphorus); manage N2 flow and tubing contamination. ⏱️🔍
• Selection guide: choose Micro‑Snyder for standardized, parallel throughput; choose blowdown for flexibility and thermal sensitivity. 🚀

Bottom line: Match analyte stability, throughput, and method mandates to boost performance and compliance. 📈✅

Compare micro-Snyder column concentration and nitrogen blowdown in EPA methods. Learn their advantages, limitations, and ideal applications.
