Testing the Waters has Never Been Easier!
If you feel like a juggler when you perform your water
testing chores, CHEMetrics can help. All of our water test systems use
disposable, self-filling reagent ampoules to simplify the process without sacrificing the
accuracy you require. Each ampoule contains a carefully pre-measured quantity of liquid
reagent that's been formulated to minimize interferences and give long shelf life. Whether
the test is colormetric or titrimetric, the CHEMetrics ampoule will take the
hassle out and give your results you can depend upon in far less time than the mix,
measure and mess method you've been used to.
CHEMet
Self-Filling Ampoules for Colorimetric
Analysis
Contents: Test kits contain 30 ampoules, comparator(s),
accessory solutions (when necessary), snap cup, and instructions. Refill packs of 30
ampoules, and accessory solutions, are available.
CHEMets ampoules are designed for maximum
simplicity and accuracy. Use them for low- to medium-range colorimetric analysis. Each
ampoule is 7 mm in diameter with a tapered, prescored tip, and reagents are vacuum sealed
inside.
The CHEMets Method: The CHEMet ampoule is immersed in the
sample and the tip snapped off. The correct volume of sample is drawn in, and a small
inert gas bubble forms. Sample and reagent are mixed by tilting the ampoule so the bubble
travels from end to end. In 2 minutes or less, the resulting color is compared to the
appropriate color standards (comparators or color chart) to quantify the result.
Low Concentrations: Less than 1 ppm. In most cases the
cylindrical comparator is used to quantify low concentrations. The filled test ampoule is
placed in the center and compared with the eight color standards around it.
Medium Concentrations: Above 1 ppm. The flat comparator
usually is used for concentrations higher than 1 ppm. The analyst places the filled
ampoule between standards until a color match is found.
Comparators have a 2-year shelf-life.
The Unique Self-Filling Ampoule
If you analyze water quality, the CHEMetrics
self-filling ampoules combine the accuracy and reliability you want with a simplicity and
elegance that is not available in other field testing methods. CHEMetrics
ampoules deliver a quantitative result you can depend on usually in 2 minutes or
less! You just immerse the ampoule in the sample, snap its tip, and compare the result
color with standards.
Available for colorimetric, photometric and titrimetric analysis,
the CHEMetrics ampoules are the easiest, fastest and safest
method available for the routine determination of over 40 analytes in a variety of
industrial and environmental applications.
Just Snap, Mix, and Compare
The unique design of the CHEMetrics ampoules
ensures a reliable result even by an untrained operator. Each ampoule contains a unit dose
of reagent to run one test. Vacuum sealing ensures that when the ampoule tip is snapped,
the correct volume of sample is drawn into the ampoule to mix with the reagent. A color
forms almost instantaneously. Compare it with color standards to obtain your result.
No Mixing, Measuring, Calibrating, or Cleaning
With the CHEMetrics self-filling
ampoules, the preparation is done for you. Each ampoule contains a premixed, premeasured
reagent that has been pH-buffered and sealed under vacuum for long-term stability. You
don't waste time and effort mixing reagents, performing complicated manipulation
completing calibrations, or cleaning glassware.
Superior Stability and Shelf-Life
CHEMetrics specially formulated
reagents and proprietary vacuum sealing provide a minimum shelf-life of 2 years for most
ampoules, which is substantially longer than competitive methods. You're also protected
against interference by carefully selected reagents and, where needed, simple accessory
solutions. With the CHEMetrics ampoules, you don't have to worry
about faulty results and money wasted on unstable or stale reagents.
Standard Methods
When you use CHEMetrics products,
you're using methods based on USEPA, ASTM and APHA standard procedures and chemistries.
For your reference, the standards used in each analyte group are documented in this
catalog.
Portable, Disposable, Refillable
Packaged with everything you need to run 30 tests, the CHEMetrics
test kits are compact and highly portable, making them ideal for field analysis. And, when
your test is completed, no special disposal is required. When you need more ampoules,
refill packs of 30 are readily available.
