| How to Avoid Out-of-Specification Results Over 50% of out-of-specification (OOS) results in analytical workflows are reportedly caused by sample processing and operator errors. Using automated Gravimetric Sample Preparation and following the Good Weighing Practice™ (GWP®) can help reduce data variability and OOS results. Find out about the benefits of Gravimetric Sample Preparation compared to traditional volumetric methods. |
| Green Chemistry - Reducing sample sizes using automated dosing An extensive amount of waste is generated by sample preparation methods in analytical laboratories. Samples are usually prepared in 50ml or 100ml volumetric flasks, and even if several injections are made, only 100 µl of solution may be required. This means that more than 99.9% of prepared solutions are disposed of without ever being used. |
| 1 in 2 OOS results can be avoided with gravimetric sample preparation Out-of-Specification (OOS) investigations in analytical R&D and QA/QC laboratories are costly and time-consuming. |
| Adhere to Accreditation Standards in Forensic Labs Weighing performance has a great impact in forensic labs. The performance of the balances, and especially the minimum weight, influence compliance with standards and can have adverse results on lawsuits. We have therefore developed Good Weighing Practice, a recommendation guideline to guarantee accurate weighing results. |
| Gravimetric Sample Preparation Uses Less Substance Typically 99% of prepared stock solutions are disposed of without being used. With Quantos QLB automated liquid dispensing modules for XP balances it is now possible to prepare sample solutions in any target container gravimetrically. Sample sizes can be scaled down by up to 90%, reducing solvent usage and waste, and volumetric flasks are no longer required. |
| Makkelijke monstervoorbereiding op bestaande balansen Het wegen van lage doelgewichten kan tijdrovend, foutafhankelijk en soms gevaarlijk zijn. Nieuwe Quantos doseermodules voor poeders en vloeistoffen kunnen worden toegepast op nieuwe of bestaande XP analytische balansen. Dit maakt makkelijke monster- en standaardbereiding mogelijk zonder het gebruik van spatels, weegschuitjes of maatkolven. |
| Geautomatiseerd afvullen van peptiden verhoogt labproductiviteit Peptides play a key role in the growing segment of biopharmaceuticals. Used in small quantities, bottling takes a lab technician a lot of time and overfilling can be very costly. The combination of QUANTOS with an auto sampler offers the ideal solution to the bottling problem: once the substance to be filled is loaded into the QUANTOS dosing head, 30 target vessels can be dosed with highest accuracy without user interaction, even with different target weights. |
| Quantos wins R&D100 Award METTLER TOLEDO has been awarded the coveted "R&D 100 Award" for QUANTOS™, a global innovation which automatically doses small amounts of free-flowing substances directly into the tare container—making weighing with a spatula a thing of the past. |
| Automated Dosing System Wins LabAutomation Award METTLER TOLEDO Quantos Dosing System QB1 wins the New Product Award 2009 from the Association of Laboratory Automation. Among dozens of laboratory products introduced each year, the world's first benchtop system for automatically dispensing small sample quantities of powders was acknowledged the best. |
