      When working with regulated environmental methods have you ever asked yourself why are all these extracts concentrated down to one milliliter (mL) final volume? This is true for most soil and aqueous methods. Of course, a few methods will require a more diluted final volume but not many.

      Have you ever worked with new methods and said to yourself “yes I know what these internal standards and surrogates are measuring and when to add them to the samples”? Sounds familiar right? Well, I remember when I first started working in the laboratory and needed to fully understand and follow all method protocols and standard operating procedures (SOPs). One of the questions I asked was, what is the difference between method 525.2 and its internal standard and surrogates versus every other method we extract and analyze?

      Have you ever had days of extracting oil and grease samples and thought to yourself “there must be an easier way to work with wastewater samples”? Whether you run oil and grease samples by liquid-liquid extraction (LLE) or by solid-phase extraction (SPE) it can be challenging at times to efficiently extract 1-liter samples due to the sample matrix.

      Have you ever thought to yourself am I using the best solid phase extraction disk offering for my application? Or can our prep lab turn samples around more efficiently if we choose a different SPE disk platform such as a single-use disk holder instead of cleaning our reusable holders? Those are just a few questions I receive when working with sample prep solutions with customers when SPE disks are brought up in the conversion.
