ATTACHING THE FIRING COTTON

In this tutorial we will show you the correct way to attach the firing cotton to the firing wire when preparing a sample for firing in any of our CAL3K Oxygen Bomb Calorimeter Systems. The exercise is fairly simple and can be completed with or without tweezers. We prefer to use tweezers as it doesn’t affect the firing cotton and sample and it’s easier to handle the firing cotton with.

CALIBRATING THE CAL3K BAYONET VESSEL

Each vessel needs to be calibrated. Although the vessels are CNC machined and very similar they are not exactly the same in electrical and thermal behaviour. Therefore each vessel must be calibrated in the CAL3K it is used in. There are a maximum of four CAL3K's per laboratory system (room). Each vessel holds four calibration fields, one for each CAL3K chassis. The fields are chosen automatically by the chassis number.

CHECK SAMPLES AND THEIR PURPOSE

A "Check Sample" is a sample which confirms the calibration. Use a Benzoic Acid (CAL2K-4-BA supplied in kit) tablet and burn it, but declare it a "CHECK SAMPLE". By declaring it the CAL3K doesn't use the Sulphur correction in the same way the calibration ignores it.

CAL3K ISOBATIC (DYNAMIC) PRINCIPLE

The CAL3K calorimeter uses both the isothermal and the adiabatic method, hence the term ISOBATIC. Digital Data Systems (DDS) invented the term to explain that the unit will work in both calorimetry methods. The method can be changed during the ignition phase. The actual method used depends on the operating parameters.

UNIVERSITY FOCUSED CALORIMETER SYSTEM

Measuring Calorific Value(CV) is very important and for students finding the calorific value in various samples in a quick, effortless and accurate way is needed. Students will have the ability to perform 9 samples per hour with our water-less CAL3K-U Calorimeter.

THE HIGHLY EXPANDABLE CAL3K-F CALORIMETER

The CAL3K-F is the fourth in the range of innovative new oxygen bomb calorimeters from DDS. The new range, from the engineers who designed the CAL3K-A Oxygen Bomb Calorimeter range, features higher speeds, improved accuracy, small footprint with the now legendary resource reduction (no water required, lower power consumption, low maintenance).

ABORT & EMERGENCY DEFLATE

The CAL3K Calorimeter has an "ABORT" function used to stop the determination in case of an emergency. To operate it from the keyboard (give it a try once you have inserted a vessel and closed the lid.) Press "Del", followed by "Esc" to Abort a Command.

MASS ENTRY

The mass is a weight in the range of 0.2g to 1.5g. The limits can be set to suit your operation. Once it is entered it is "LOCKED" in to the present operation until it is ignited. The only way to "ERASE" the mass or "UNLOCK" it is as follows

START A "CHECK SAMPLE"

It is recommended to run a "CHECK SAMPLE" at least once a day at different times. Both the Calibration and the Check Sample are saved in the 32 long calibration history field, ready to be used for "IntelCal" computer calibration.

COTTON & WIRE CORRECTION

The sample is ignited by sending a current through the firing wire. This makes the wire glow, which in turn ignites the cotton thread, which in turn ignites the sample. The cotton and wire correction compensates for the electrical firing wire energy and the energy of the burned cotton. The default setting is 0.1ºC.

BALANCE MASS ENTRY WITH THE CAL3K-A

In this lesson we use the CAL3K-A Oxygen Bomb Calorimeter System and a Sartorius balance to automatically enter the weight of a sample into the CAL3K-A Calorimeter before a sample determination.

INTRODUCING THE CAL3K-A FEATURES

A brief overlook at the CAL3K-A features and benefits, including : improved accuracy, higher speed, environmentally friendly, no water required, temperature control, no air-conditioning required, self sealing and self locking bayonet vessel, adiabatic calorimetry method, isothermal calorimetry method and an external oxygen filling station.

NEW LOOK MANUAL OXYGEN FILLING STATION

The station is manufactured completely in house which saves on costs and results in a reduced final price. It is light weight making it a lot easier to transport from place to place if needed. It is a lot easier to handle and safe (user-friendly). Being manufactured with different materials to those used before, makes it kinder to the environment (environmentally - friendly).

FILLING & DE-FILLING THE OXYGEN VESSEL

The following method applies to the following oxygen bomb calorimeter systems : CAL2K, E2K, ECO, CAL3K-A, CAL3K-U, CAL3K-F. The CAL3K-AP uses internal automatic oxygen filling, which does not require the manual oxygen filling station.

ACCESSING SAMPLE & GROUP ID

The sample ID is a 16 character (or shorter) string of characters on the CAL3K Oxygen Calorimeter used to identify a sample determination. The last character will be automatically incremented at each firing. That is to say that a 5 is incremented to 6, and “C” increments to “D”. If a short SID is used, followed by spaces, then the last non-space character is incremented.

READING THE CAL3K CHASSIS NUMBER

The Chassis name and number are required to identify your chassis. However, both have nothing in common. The name can be set via the USB PC port, the number is set automatically by the factory and it is unique. Therefore, the name must be set when : - A Bluetooth adapter is used with the CAL3K system.

CAL3K WATERLESS BAYONET VESSEL

Why Choose a Waterless Calorimeter? Traditionally water is used in adiabatic and isothermal combustion calorimeters. It is used as a heat sink, as a transfer medium, or as a transport medium. In short : A calorimeter will combust a weighted sample in a steel cylinder and measures the resulting temperature increase. From the temperature increase it calculates the Calorific value. Somewhere in the process the apparatus must minimize/prevent or calculate the temperature losses to the environment.

CAL3K AIR COOLER & FEATURES

The new Air Cooler replaces the traditional expensive water cooler used with the CAL2K range of calorimeters. It uses less resources, including no water and less electricity, to operate. The air cooler works with the ambient air to cool the vessel down, ready for the next determination. Best of all, the air cooler is extremely fast and efficient and affordable when measuring heat of combustion.

COOLING THE CAL3K BAYONET VESSEL

After running a sample, once the determination is complete, the CAL3K Oxygen Bomb Vessel can be removed from the calorimeter. Before de-filling or preparing the bomb for the next firing it needs to be cooled – this is done using the CAL3K Air Cooler (supplied with most of our calorimeter systems). To start the cooling process, remove the bomb vessel from the calorimeter, make sure the air cooler is powered up, and placed the warm bomb vessel into the air cooler. The air cooler will automatically start cooling the vessel with air. Once the air cooler prompts that the vessel is “Ready for use” the bomb vessel can be removed, de-filled, opened and inspected before the next determination.
