Shimadzu's LCMS-8065XE for PFAS Analysis in Chicken Tissue

Total Coliform Analysis using Membrane Filter Assembly. Performed total coliform analysis of water samples using the membrane filtration technique. The method involves filtering a measured volume of water through a sterile membrane filter, placing it on selective growth media, and incubating it to detect and enumerate coliform bacteria. This technique helps assess the microbiological quality and safety of water.

PFAS in biosolids remains an area of growing interest and knowledge. Six states have interim thresholds for biosolids (CO, MD, MI, MN, NY, and WI). Maine banned the application of biosolids in 2022 due to PFAS concerns. The Interstate Technology & Regulatory Council (ITRC) continues to assimilate the latest information on PFAS and biosolids into their guidance. If you are interested in the latest report from Maine on PFAS in biosolids, the full assessment report is available online - Assessment of PFAS Levels in Washington State Biosolids, Publication 25-07-057, September 2025. This chart from the report provides a quick snapshot of PFOS in dewatered biosolids from the study in Maine compared to interim threshold values in Colorado and Michigan.

This month in Ultrafine Bubbles: Recent testing adds further confidence to the safety of ultrafine bubbles for human consumption. Japanese researchers conducted a comprehensive safety evaluation of water containing air filled UFBs that was measured, transported, and stored according to ISO standards. They used internationally recognized OECD testing protocols to assess safety across three exposure routes: 𝐒𝐤𝐢𝐧 𝐂𝐨𝐧𝐭𝐚𝐜𝐭 𝐓𝐞𝐬𝐭𝐢𝐧𝐠 – No irritation observed 𝐄𝐲𝐞 𝐜𝐨𝐧𝐭𝐚𝐜𝐭 𝐭𝐞𝐬𝐭𝐢𝐧𝐠 – No irritation or damage observed 28-𝐝𝐚𝐲 𝐨𝐫𝐚𝐥 𝐢𝐧𝐠𝐞𝐬𝐭𝐢𝐨𝐧 𝐬𝐭𝐮𝐝𝐲 – No toxicity detected This study adds to the growing body of evidence supporting the safe and effective use of UFBs in consumer products for delivery of beneficial compounds. #ultrafinebubbles #nanobubbles

Important new research out of Japan further demonstrating the safety of water infused with UFBs for human use.

Why contact playes are 55 mm and settle plate are 90 mm in diameter: Here’s the explanation for why contact plates are 55 mm and settle plates are 90 mm in diameter. Both are standardized sizes used in microbiological environmental monitoring: 🧫 1. Contact Plate – 55 mm Purpose: Used for surface monitoring (e.g., walls, equipment, gloves). Reason for 55 mm size: Designed to fit comfortably on curved or flat surfaces. Provides adequate surface area (≈24 cm²) for detecting contamination without spreading too much agar. Easy to handle with one hand during sampling inside controlled areas (like cleanrooms). Standardized by pharmacopoeias (USP, EP, ISO 14698) for reproducibility and comparison across labs. 🌫️ 2. Settle Plate – 90 mm Purpose: Used for passive air monitoring (to collect settling airborne microorganisms). Reason for 90 mm size: Larger surface area (≈63 cm²) allows more microorganisms to settle over a typical 4-hour exposure period. Matches the standard Petri dish size used for microbial culturing, making incubation and colony counting easier. Provides consistent data for trending and regulatory acceptance (per WHO, EU GMP, and ISO guidelines). 📏 In short: Plate Type Diameter Approx. Area Reason Contact Plate 55 mm ~24 cm² Surface monitoring, easy handling Settle Plate 90 mm ~63 cm² Air monitoring, larger exposure area.

Microbiological Water Testing Setup Vacuum Filtration Assembly Detailed view of the membrane filtration assembly used for microbiological analysis of water samples. ✓ The apparatus includes a sterile glass or stainless-steel filtration unit comprising a funnel ✓ A membrane support base. ✓ A 0.45 µm pore size membrane filter held in place by a clamp. ✓ The assembly is mounted on a vacuum flask connected to a vacuum pump which creates negative pressure to draw the water sample through the membrane. ✓Microorganisms are retained on the membrane surface, while the filtrate passes into the flask. After filtration, the membrane is aseptically transferred to a selective agar medium for incubation and colony counting.
