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.

Accurate liquid chromatography (LC) results start with the right water. Even the smallest impurities can impact reproducibility, sensitivity, and data reliability.

Protein powder that clumps or won’t mix? The answer isn’t always in the shaker bottle – let’s check the lab! MICROTRAC SYNC laser diffraction with image analysis shows us particle size and shape, which affects water absorption, flowability, distribution, and handling. Smooth blending starts here. Then the Velp Scientific Kjeldahl method checks protein content, making sure the label matches what’s inside. Because if your protein powder doesn’t flow, mix, or fuel you right… what’s the point? 😉 #ProteinPowder #ParticleSize #LaserDiffraction #Kjeldahl #ProteinDetermitation #NitrogenDetermination #SYNC #Microtrac #VelpScientifica #ATSSci

Just in time for Halloween, a post about spirits. 👻👻 No, not the disembodied apparitions that haunt spooky old mansions, but the distilled libations that are enjoyed neat, on the rocks, or in cocktails. 🥃 🍸 A new Agilent application note describes a fast GC method to determine 17 alcohols, aldehydes, esters, and organic acids using the Agilent 8850 GC with an FID. The high-speed analysis was achieved using a 10-meter column and the GC's rapid oven heating and cooling capabilities. Helium, hydrogen, and nitrogen were evaluated as carrier gases. Cycle times using helium and nitrogen were reduced to about one-third that of the traditional method, while hydrogen exhibited a five-fold improvement. Long-term stability experiments showed that even after 2,000 injections, the retention time remained consistent, and all target peaks remained sharp and symmetrical with consistent and effective separation.
