Sherwood Scientific Ltd. at ACHEMA

With a 50% increase in stand area Sherwood was able to show six new products as well as several existing ones.

The three new programmable CHROMA Colorimeters (see separate News release) were well received but the stars of the show were the Model 410 Flame Photometer extensions.

Module A allows any Model 410 in the field to be updated, enabling printing of Blank, Calibrator and Sample readings with date and time.

Module B really extends the utility of the Model 410. this plug-in module allows collection and correlation of data from the 410 within the software package (supplied with the module) and also, through software control, allows incorporation of the Model 860 Autosampler.

Another new product, the Model 926 Salt Analyser also features Bluetooth with LIMS capability. Productivity improvement by 50% is the target outcome when used in conjunction with the HP IPAQ and Dell handheld PDAs.

Sherwood has trademarked the Module B and the Salt analyser as .

Probably our main purpose of attending such international shows is to meet our extensive dealer network. At ACHEMA we met 34 existing Distributors. Our picture shows colleagues from Egypt and Poland together with David Ruxton, Jon Copsey our Marketing Manager and Stan Bogdanski.

Sherwood Scientific recently shipped 66 of their new Model 260 Programmable Colorimeters to satisfy an International Tender for Bilirubinometers.

The Model 260 can be programmed for the vast majority of clinical chemistry tests. It is an open system and this shipment was accompanied by reagents manufactured in France by Seppim.

Chloride will be domonstrated for the first time in North America at the International Association for Food Protection, held this year in Calgary, Alberta from August 13^th to 15^th.

The Picture shows the Model 420 in use at the University of Wales Hospital in Cardiff with Heather Wheatley who developed the protocol with Sherwood Scientific.

Sherwood already supplies its Model 926s Chloride Meter as the level of chloride confirms the diagnosis of Cystic Fibrosis on sweat samples. In addition to the chloride content many biochemists like to see the potassium and sodium levels as well. The Sherwood Model 420 Dual Channel flame photometer is ideal for this task.
Now the new formulation of Lithium Internal Standard, with Cl levels below 0.5 ppm, means that a combined protocol can use the same sample for chloride, sodium and potassium.
The part number of the Lithium Internal standard concentrate (00156603).

In the future the Model 420 is intended to replace an Eppendorf instrument measuring directly concentrations of up to 20 g/l KCl and 1 g/l NaCl in drinking water without a dilution step. Blanking, calibration and sample streams will be automatically introduced into the instrument and results are will be triggered remotely.

The main advantages are:

The Sherwood Line of Flame Photometers is suitable for two other ASTM methods

D 3340-98(2003)	Lithium and sodium in lubricating greases.
D1318-00	Sodium in residual Fuel Oil

Standards

These are precise and accurate formulations with Certificates of Analysis and dates of expiry. This is to re-assure the users that when they use the solution they can rely on the nominal value to calibrate their instrument.

The date of expiry refers to an unopened bottle. We are asked about the length of time a solution has validity after it is opened. It is impossible to give an absolute answer as it depends on the temperature, how often the cap is removed, the volume remaining in the bottle and of course the way in which the solution is dispensed. The main change in concentration would occur through evaporation of the solvent when the container is left open to the atmosphere, thereby increasing the concentration of analyte.

The correct way to use a standard solution is to open the bottle, pour out a sufficient quantity into a clean dry beaker, immediately replacing the cap on the bottle. The calibration is performed using the aliquot in the beaker. Following use, the remaining standard is discarded and not returned to the standard container.

Active reagents

These include the Acid Buffer (00156208) for the Model 926 series chloride meter, and the Diluent Concentrate (00156681) used as a dilution aid for the Flame Photometers, especially when used with the Model 805 Diluter.

These are also batch controlled for purity of ingredients and have an expiry date as they are used in the carrying out of measurements and, therefore, can affect the result.

Cleaning preparations

Disinfectant solution (00156682), and Cleaning solution (00156184) are under batch control but do not need an expiry date as their potency for effective cleaning is long lived. The Deproteinising solution (00156183), should be made up by adding the sachet to the solution component. This combined solution can be kept refrigerated for 4 weeks.

The business moved to its present location in Cambridge in 1996 to cope with the addition of the Corning products.

Our latest expansion project has enabled us, to make more efficient use of available space, double the workstations and increase the storage and work-in-progress areas. This coupled with redecoration of the workspace and communal areas have led to an environment that promotes greater productivity.

As Sherwood operates a "make to stock" batch manufacturing environment the redevelopment of the space encourages more efficient production processes helping Sherwood to remain flexible and more able to respond to changes in customer demand
