What are the Advantages of Sieving?

What is a Test Sieve A test sieve is an instrument that is used for the measurement of particle size. In its most common form, it consists of a woven wire screen, with square apertures, rigidly mounted in a shallow cylindrical metal frame. For coarse sieving, a perforated plate screen with square or round holes may be used in place of wire mesh. Square hole perforated plate sieves range d...

Which filters are best to prepare samples for heavy metals analysis?

Filtering water samples before ICP-MS or HPLC analysis for heavy metals testing is good practice - to help protect these delicate instruments from damage caused by larger particles. However some filters can introduce interferences which may affect the results - so what type of filter is best for heavy metals analyses? Why filter samples? Samples taken in the field are often high in...

What is a liner-less bottle? When would you choose a liner-less design bottle?

Sample storage bottles are sometimes described as "liner-less" - this means that the cap does not have an inner lining. This liner is usually present to improve the seal between the cap and bottle, but can present cross contamination risks in some cases. [caption id="attachment_11167" align="aligncenter" width="495"] As seen above, sample bottles or storage bottles can come with lined (le...

How can I measure Chemical Oxygen Demand (COD)?

A chemical oxygen demand (COD) test is used to measure the amount of organic compounds in a water sample. It measures the capacity of water to consume oxygen during the decomposition of organic matter and the oxidation of inorganic chemicals such as Ammonia and nitrate. The most common method uses COD vials with overall results being achieved in approx 2-3 hours. Before you start, make sure ...

How to guide: Hydrometers & Brineometers

A hydrometer measures the specific gravity of liquids. It looks at the ratio of the density of the liquid it is placed in compared to the density of water. They are usually made of a glass cylindrical stem adjoined to a weighted bulb which floats when placed in solution. By carefully placing your hydrometer in a sample of your solution you can take the measurement on the scale where it breaches...

Question: How can I measure the salinity of Brine?

Answer: a Brinometer! Brine is simply defined as a solution of salt in water. It has a wide variety of uses from the transport of thermal energy, de-icing the roads or in cooking to preserve meat or vegetables. The low levels of salinity commonly found in food or seawater can be tested in a number of ways such as on the Laqua Twin sodium meter , Laqua Twin salt meter or for a multi-pa...

How can I keep my pH buffers working reliably

pH Buffers are aqueous solutions with well defined pH values and have a 'buffering' capacity to maintain pH even when small quantities of acids or bases are added to them. Having a known pH value, buffers can be used as a standard to calibrate pH Meters and therefore keep on-going measurement taking accurate and reliable. To keep these statements true you need to make sure your buffers are in d...
